MiniWarden OVERVIEW
SeaSideAutomation, with over 20 years of technological leadership in Pool & Spa Chemical Control
Systems congratulates you on your selection of the MiniWarden Chemical Controller. MiniWarden is a
water chemistry control system with capabilities to control the pH and sanitizer on a pool, spa, fountain or
any other similar body of water. Using ORP (oxidation reduction potential) technology the control of
sanitizer takes into account the eects of pH and a pH lockout feature is also included for high pH
values.
Supporting both 110 and 220 VAC, the MiniWarden will control chemical feed equipment using relays to
keep the pool or spa water in balance. Water measurements are taken continuously while MiniWarden's
internal relay programing determines if chemical adjustments are needed. MiniWarden also contains a
selection for the sanitizer relay to be dry-contact which can be used for salt water chlorine generators and
solenoid valves that are controlled with a dierent voltage or a simple switch.
SYSTEM COMPONENTS
Simple and Advanced operating modes: SIMPLE: Cycle time control makes the MiniWarden very easy
to operate and only a few settings required for operation. ADVANCED: The original operating modes
allowing for very detailed and precise control.
CONTROLLER: MiniWarden is a microprocessor based, modular automation system that is
capable of continuous monitoring locally onsite or remotely osite.
INTERFACE: MiniWarden uses a 16-button built in keypad, and an easy to read 80 character
liquid crystal display. The display’s internal back-light provides controller viewing in pool rooms with low
light conditions. Back-light illumination time can be adjusted to suit the operator.
MEMORY: MiniWarden is designed with nonvolatile memory which preserves all internal programming
in case of power loss. Internal memory is preserved for up to 10 years without having power applied.
RELAYS: MiniWarden includes 2 output relays for the control of pH and sanitizer.
SENSORS: ORP Sensor, pH Sensor, Temperature Sensor and Flow Sensor.
VOLTAGE: MiniWarden requires 120/220 VAC Input Voltage to operate.
SECURITY: MiniWarden is designed with a lockable enclosure and provides up to four levels of
password security protection (Admin, Tech, Service and Guest) for both local onsite and remote osite
interaction with the controller with 10 passwords.
COMMUNICATION: MiniWarden can connect to the Internet for direct monitoring, setup, and data
interface via an Ethernet option (a WIFI bridge can be added for wireless).
DATA: MiniWarden will record up to 8192 lines of data with the built in internal memory.
OVERFEED PROTECTION: MiniWarden is designed with overfeed protection. Standard Overfeed
limits the amount of time a relay can turn on feed equipment in a 24-Hour period. Also includes a
setpoint overfeed limit that can be used to prevent chemicals from being fed onto the oor of the
equipment room by damaged feed tubes.
PROPORTIONAL FEED: Proportionally reduces the on-time as the measurement gets closer to the
set-point to prevent overshoot.

MiniWarden INSTALLATION
Mounting MiniWarden
Turn o any heaters, pool or spa circulation systems, chemical feed pumps or any related shut-o valves
or equipment and relieve pressure from the ltration system. Find a suitable mounting location near a
120/240 VAC power source that meets the following criteria:
●Facilitates a combined (inuent & euent) maximum tubing run of 30’.
●Do not mount controller above electrical sources or electrical equipment.
●At least 10’ away from any pool, spa or body of water and not accessible to the public.
●Away from corrosive materials and physical hazards.
●Not in direct sunlight or directly above or near any heat source.
●For 220 VAC, ability to hard wire with GFCI (ground fault circuit interrupter) protection.
Securely mount controller or the optional controller backboard vertically on the wall using supplied screws
or appropriate fasteners for the wall construction. Never mount MiniWarden horizontally.
Flow Cell To Circulation Plumbing
There are many ways to connect the ow cell tubing to the circulation plumbing. Successful ow cell
installation requires a pressure dierential. One way to install is to make sure the input source to the ow
cell is well upstream from any chemical injection point (C Below). The Flow cell input and output points
before and after the lter provide the greatest pressure dierential (see below). MiniWarden is equipped
with a strainer to lter out any debris from the unltered water. Periodically check and clean the strainer.
However, the ow cell input and output can also be installed before and after the heater if enough pressure
dierential is available to create adequate ow through the ow cell.
●Flow Cell Input: Drill & tap a connection point in the circulation system at a location just up-stream
from the lter (A - Below). Install tubing connector and run tubing to the input side of the ow cell.
●Flow Cell Output: Drill & tap a connection point in the circulation system at a location with reduced
pressure just after the lter (B - Below). Install tubing connector and run tubing to the output side of
the ow cell.
CAUTION: Maximum pressure across the sensors should be 10 PSI (pressure gauge may be required).
Always expose the sensors to positive pressure. Prevent exposing the sensors to negative pressure or a
vacuum by connecting the ow cell output tubing to the suction side of the pump as the vacuum may suck
the sensor gel from the sensors rendering the sensors inoperable in a very short period of time.

MiniWarden Manual 530-487-5007 8
If not pre-mounted, nd a suitable location to mount the acrylic
ow cell within 3 feet of the controller. Mount and assemble ow
cell parts according to Picture 2.
There is a small magnet in the ow cell that is held in place with
a piece of tape. Remove the tape and make sure the magnet
remains in the hole above the lter / strainer.
Remove pH (Blue) and ORP (Red) sensors from the boxes. Use
Teon tape on sensor threads and all other ow cell parts to
ensure water tight connection and fasten accordingly.
Install the appropriate 1/2” or 3/8” hard vinyl input and output
tubing from the pools circulation system connection points to the
“In” and “Out” connection points on the ow cell according to
Picture 2.
Once connected, turn circulating pump back on, test for leaks at
all connection points, and make sure all air evacuates form the
tubing.
IMPORTANT NOTE: There needs to be just enough water ow
through the ow cell to raise the ow magnet inside the ow cell to
make contact with the ow sensor. To test this, turn the “input”
shut-o valve to the o position and watch the ow magnet drop
from the ow sensor. Next, turn the input shut-o valve back on and
watch the ow magnet raise to the ow sensor. If the ow magnet
raises abruptly and pings/knocks the ow cell acrylic then there is
too much ow pressure. To reduce pressure, perform the same
exercise, but now open the shut-o valve slowly and stop when you
see the magnet “slowly” raise to make connection with the ow
sensor. Leave the shut-o valve in that position.
Sensor Wire Connection
If not pre-mounted, route the pH (Blue Sensor Wire), ORP (Red
Sensor Wire), gray ow switch and the gray temperature sensor
wire through the small cable grip on the right side on the bottom part
of the controller and connect as labeled inside MiniWarden or as
indicated below in PICTURE 3. Please Note: Black wires are
always negative (-) and the Clear or Red wires are always
positive (+).
●Flow Sensor Connection: Connect ow the sensor to Flow1
on the display board on the lid.
●Temperature Sensor Connection: Connect the sensor to the
Temp connection on the display board on the lid.

MiniWarden Manual 530-487-5007 9
Supply 110/220 Vac Input Selection
The MiniWarden supports both 110 VAC and 220 VAC. For 110 VAC the power cord includes a GFCI on
the end of the cord that plugs in. For 220 VAC the cord should be removed and the MiniWarden should be
hardwired to a circuit breaker with a GFCi by a licensed electrician. The cord can be returned to
ControlOMatic for a credit.
●VAC Selector: The red switch on the left of the bottom circuit board must have the switch notch up for
110 VAC, and down for 220 VAC. Incorrect selection will damage the MiniWarden.
●A good solid earth ground is required for MiniWarden to work properly.
●The ORP and pH relay are directly connected to the input VAC. If you have the MiniWarden set for 220
VAC then the loads must also be 220 VAC.
●For 220 VAC operation, the neutral line will be connected to the Red 220 VAC wire and the Line
connection will be to the Black 220 VAC wire. The Neutral connection for pH and ORP relays switches
the Neutral input VAC wire. The relays are double through and break both lines.
Load / Equipment Connection & Installation
ORP & pH RELAYS: The chemical feed relays for pH and ORP are internally connected to the
input VAC main input which is located on the left side connector on the circuit board through 5 AMP fuses
F1 and F2. No voltage is being supplied to the load / equipment when the relay is o, hence, voltage is
being supplied to the load / equipment when the relay is on. Any standard chemical feed pump or solenoid
valve can be hard wired directly into the appropriate ORP and pH connection terminals as shown below in
PICTURE 4 so long as their voltage matches the input VAC connected to the MiniWarden.
Relay Board Acronyms for ORP & pH 120 VAC Relays:
❑Line: Normally Open Black. When the ORP & pH relay is o the terminal will have no voltage.
Hence, when the relay is on the terminal will have voltage.
❑Neutral: For 110 VAC - This is connected to the input white neutral wire when the relay is on. For
220 VAC - This is connected to the neutral connection on the VAC input terminal which is connected
to the 220 VAC red wire.
❑GND: The ground connection for the ORP and pH chemical feeders.
❑ORP NO: The connection to the relay that is normally open. When the relay is o there is no
supplied voltage, only when the relay is on.

MiniWarden Manual 530-487-5007 10
❑ORP NC: The connection to the relay that has voltage when the relay is o. When the relay is on
there is no voltage.
ORP DRY CONTACT RELAY
A dry contact relay is not connected to any voltage and acts as a switch. To supply power to a load /
equipment (such as a chemical pump) through a dry contact relay, the voltage must be supplied
using a jumper to the appropriate voltage. To change the ORP relay to dry contact the Dry Contact Switch
must be switched to the upper position. In this case, when the relay is on the Line connection will be
connected to the Neutral connection when the relay is on. For the control of a saltwater chlorine generator
the dry contact can be used as a switch with no voltage.
Relay Board Acronyms for the ORP Dry Contact Relay:
❑Line: One side of the dry contact relay. ❑Neutral: Other side of the dry contact relay
❑ORP NO: Line is connected to Neutral when the relay is on.
❑ORP NC: Line is connected to Neutral when the relay is o.
Supported Auxiliary Dry Contact Loads / Equipment:
Chlorine Generators: A high power chlorine generator should not be powered using MiniWarden’s
internal VAC power as it may exceed the input 2.5 AMP relay rating. One way is to break the chlorine
generator ow switch line (B) as shown in PICTURE 5. When MiniWarden’s relay turns on while the
ow switch is on then the chlorine generator will turn on. When the relay is turned o it makes the
chlorine generator think there is no ow and the chlorine generator will turn o.
Loads / Equipment Using External 24 VAC (Erosion Feeders & Suction Side Cal Hypo): Solenoids are
used to control water ow through a chlorine erosion feeders and suction side cal hypo systems and
may use 24 VAC. Install a 24 VAC Transformer external to the MiniWarden and connect one of the
output leads to the Line connection of the ORP relay and connect the Neutral connection of the ORP
relay to the solenoid as shown in PICTURE 5. Connect the other 24 VAC Transformer wire to the
remaining solenoid wire (C). If the 24 VAC Transformer has an output ground wire then connect it to
one of the GND terminals on the relay board.

Manual Feed: Use the up and down arrow keys to scroll next to the relay that needs to be put into manual
mode. Press the Enter button or the Right Arrow to put the selected relay into manual mode. There are three
states that the relay can be in when in manual control:
If the relay is currently ON, it will turn o for the amount of manual relay time in the relay setup. Once this time
is nished the relay will go back to auto.
If the relay is OFF, and not in manual OFF mode, it will turn ON for the manual relay time and return to auto.
If the relay is OFF, and not manual mode, it will go back to auto.
Alarms: Select this menu to set the high and low alarms for ORP and pH.
1. When the pH or ORP is outside of the limits, there is a xed 1 minute delay before the alarm red LED will
turn on. If this is the only alarm condition, the LED will be on solid.
2. If the feed limit has been reached, there will be an “s” for the Relay status the the alarm LED will be
ashing.
Data: See the description in the advanced mode section. Data recording is the same except the interval is
xed at 1 minute in simple mode.
RLY: This is the advanced relay conguration and can be used to change values outside of the simple mode
method. - This menu choice will be removed.

Time Proportional Control:
With Time Proportional Control (TPC) the relay will cycle ON for part of the cycle
time (either 30 or 60 seconds) depending on the deviation from the set point.
The smaller the deviation, the less time the relay will be on. TPC helps to
minimize overshoot and provide a stable approach of the chemical values to reach
the set point.
The spread sets the distance from the set point that TPC will be in control before
the relay is strictly on or o. Increasing the spread will help to reduce overshoot
and if it takes too long to reach the setpoint then decrease the spread.
ORP and pH Spread - ON/OFF Control:
Setting the spread to 0 disables TPC and the relay will on when the setpoint needs to be reached and o when
the measurement equals or has passed the set point. On/O control is typically used when the feeders are
slow or under sized such as erosion feeders and salt systems or if the volume of the water is large.
Feed Cycle: The feed time is the total of the on and o times added together and remains the same. When
the cycle time is reached it will just start over. There are two cycle times to select from and 30 seconds is
typically for spas and 60 is for pools.
pH Control: Select either Acid or Base. For Acid, the pH relay will be in a feed cycle when the pH is higher
than the set point. For Base, the pH relay will be in a feed cycle when the pH is lower than the set point.
pH Lockout: A protection setting for sanitizer control. If set to O pH Lockout is disabled. The selections are
O, 7.8, 7.9 and 8.0. If enabled and the pH is greater than the value, the ORP relay will not turn on.
ORP and pH Feed Limit: Feed limit is a time limit for the set point to be reached. Some of the common
failures of a chemical feed system are running out of the chemicals, chemical feed system failure and even
broken chemical feed tubes. If the relay is on for the selected time without the set point being reached the
relay will be disabled until the condition is corrected or the feed limit timer cleared. Use one of the following
methods to clear the timer:
1. Manually adjust the water to get the measurement at the setpoint. This can also be accomplished via
calibration or changing the setpoint.
2. Cycle power on the MiniWarden
3. Go to the Relay Information menu in the Handy Menu and press the number 0 on the appropriate relay to
clear all the timers.
Time and Date: Enter the current time and date that will be used to time stamp the data.
Password: Simple mode allows for 1 password. If the password is 0 the feature is disabled. When there is a
password, it will be required to access the main menu. After entered, it will clear and need to be re-entered
when the back light turns of which is 2 minutes with no buttons pressed.

Step 3 - Relay Control Type Menu
The Relay Control Type Menu is the next step in programming MiniWarden and getting started. The Relay
Control Type Menu sets each relay to the control type the relay will use. For Example: Will the ORP Relay
use Liquid Chlorine, an Erosion Feeder or a Salt System? This is where the MiniWarden relays are set up
to the appropriate way to control the installed equipment. From the Default Readings screen press the
Back button to scroll down and select Relay Control Type and scroll down to the relay that needs to be
changed and press the Enter key to select that relay. When changing a relays control type the Arrow
buttons perform the following actions which is also indicated on the screen.
Press the ► Right Arrow to cycle through all the control types for the current relay.
Press the ◄ Left Arrow to save and update the new control type within MiniWarden. Note: The Back
button will cancel the change, only the Left Arrow will change the control type. Note: To reset a single
relay back to factory default values select that relay in this menu and the press the Left Arrow.
Press the Back button to cancel and exit without making any changes.
Relay Control Types: MiniWarden includes control types for sanitizer and pH. The ORP relays can
only use a sanitizer control type and the pH relays can only use a base or acid control type.

ORP Relay:
In the Relay Setup Menu scroll down to the ORP relay and press enter.
The following reviews each command within an ORP Relay selection that is
setup as Liquid Chlorine (the control type can be changed in the Relay
Control Types Menu) . The other less common control types such as Cal
Hypo, Salt Systems, etc follow a very similar relay programming and
command structure as Liquid Chlorine. Please use the following as a guide
for those less common control types.
Manual Time 00:02:00: Is the amount of time you can set a relay to turn
on manually (Default Setting 2 Minutes). To turn the relay on manually
you have to do so in the service menu which will be covered in the next
section. When you turn on the relay manually in the service menu, the
relay will be on for 2 minutes in this case. To change the time, simply
enter the new time and press Enter to save.

Proportional 10%: The Proportional %-Age
(Default Setting 10%) means that as the
measured ORP reading gets to within 10% (630
in this case) of the ORP setpoint (700 in this
case), the amount of relay on-time will
proportionally decrease as the reading gets
closer and closer to the setpoint. Proportional
feed helps to prevent chemical overshoot. To
change the %-Age, simply press Enter, change
the value and press Enter to save. To disable, set the %-Age to zero “0” and press Enter to save.
On If ORP < 700: This is the ORP setpoint and the factory default setting is 700. The relay will
turn the chemical feed pump on if the measured ORP reading is less than 700. The relay will turn on
for the programmed on time, in this case for 1 minute as set in the “On Time 00:01:00” command or
less than 1 minute if the measured reading is within the proportional feed %-age of 10%.
O If pH > 0.00: This is the pH Lockout Command. The default setting is zero “0” or disabled. ORP is
highly dependant on pH. In other words, a high pH reduces the killing eectiveness of the sanitizer and
has a direct eect on lowering the ORP reading even though there is already an ample amount of
sanitizer in the pool. The pH Lockout feature helps to prevent chlorine overfeed. A typical pH Lockout
setting is 8.0 and will lockout the ORP relay when pH reaches 8.0 or higher. The default setting is 0.0 or
disabled.
On Delay 00:00:20: The on delay, in this case 20 seconds, is necessary to prevent the relay and
hence the chemical feed pump from turning on and o frequently if the sensor measurement uctuates
back and forth from 699 and 700. It means that the relay will not turn on unless the condition of “On If
ORP < 700” is satised for at least 20 seconds - then the relay will turn on for the programmed “On
Time 00:01:00” in this case 1 minute. To change the on delay time, simply press Enter and change the
time and press Enter again to save the new setting. Enter 00:00:00 to disable.
On Time 00:01:00: This is the total amount of time the relay will be ON if the “On If ORP < 700”
condition has been satised. The default setting is 1 minute. This command works in conjunction with
the MinTimeO Command below. If the ORP reading is not being maintained then more or less on time
may be needed.
MinTimeO 00:07:00: This is the total amount the relay will be OFF if the “On if ORP < 700” condition
has been satised. This is the amount of time allowed for chemical mixing in the pool and works in
conjunction with the “On Time” Command above. Do not set to 00:00:00 if the On Time is not also set
to 00:00:00 as they work together.
