UCA/W/H/R Introduction
This document outlines the quick start procedure for items that require conguration at initial system startup.
Additional ne tuning may be required depending on the system’s application.
This guide assumes the required software is installed on the CoolLogic Touch Controller and each of the Chiller
Modules in the bank. It is important to verify that all sensors’ input jumpers on the CoolLogic Touch and Module
Controllers are set properly per sensor type used (voltage, thermistor/dry contact, or current loop).

Establishing Communication and
Conguring Modules Present
Use this guide after the software is installed and all devices are properly addressed. Address the
CoolLogic Touch Controller and Modules using the rotary dials on each control board. All control
boards require a power cycle after setting the address.
IMPORTANT: Save Settings.
After all conguration items are set as desired for the chiller bank, access the Conguration Screen
to save settings.
System Setup →Controller Conguration and select Backup Memory to save your settings.
After applied, verify the “VALID?” Indicator turns green.

Models:
UCA/W/H/R Conguring System Type and Application
Select System Setup from the Home Screen.
Chiller Module Type: Select the appropriate module type from the following options: UCW, UCH, UCR, UCA,
UCA-UCF, UCA-HP, UCH-HP, UCH-HR.
Chiller Control Type: Make your selection based on the bank application from the following options: Cool
Mode, Heat Mode, or Heat Recovery.
Chiller Control Source: This selects the start/stop method the chiller bank uses.
Keypad – Enable using the keypad and the three-way switch in the LOCAL position.
Digital Input – Enable with dry contact closure of the Remote Chiller Enable terminals within the
CoolLogic Touch Control Panel and the three-way switch in the REMOTE position.
BAS – Enable via BACnet points and the three-way switch in the REMOTE position and the contact closure
at the CoolLogic Touch Control Panel terminals 42 and 43 of LVTB1.
Enable Chiller from Keypad: Enables chiller operation when the three-way switch is in the LOCAL position
(both must be ON for the unit to run).
Use High Ambient Temp Limit: When ON, this disables unit operation in high ambient temperature conditions
(default 115°f). For UCA/UCF banks only.
Disable Heating Below: The ambient temperature setpoint below which heating is disabled. This applies only
to air source units. For UCA Heat Pump banks only.
Disable Cooling Below: The ambient temperature setpoint below which cooling is disabled. This applies only
to air source units. For UCA/UCF banks only.

COOL AND HEAT SETPOINTS
Under Local, select Hot (or Cool) water setpoint
and enter the desired setpoint for each mode. The
Min/Max for Load/Source Out is for bank safeties
where a breach in these values disables the unit
from running.
Input 8 and Input 10 settings are related to the
remote setpoint control functionality on the
CoolLogic Touch Controller.
FREE COOLING SETUP
Free Cooling Setup is the required conguration to
set up the UCF modules’ operation in a bank.
Enable Free Cool Modules: Enable Free Cooling if
Free Cooling modules are available.
Enable Free Cool Below: The maximum temperature
at which Free Cooling starts.
Enable Free Cool Above: The minimum temperature
at which Free Cooling stops.
Disable Free Cool Lockout: If the outside ambient
temperature (OAT) is less than the low ambient
temperature trip point, Free Cooling is disabled if this
option is selected.
Run All Free Cooling Modules Together: All Free
Cooling Modules stage up together instead of
waiting for each UCF to stage up individually.
The next UCF stages up only if the previous UCF
module is at max capacity (full fan speed) for at
least ve minutes.
Disable Mechanical Cooling: Enabling this disables
Mechanical Cooling from UCA modules when Free
Cooling is Enabled.
Water Valve Open Below OAT: The OAT setpoint
for Freeze Safety. When the OAT is at or below this
setpoint, the open/close water valve opens and the
mixing valve opens to the pre-set position.
Mix Valve Open Amount (3-8): The Mixing Valve
Position when Freeze Safety occurs.
Use UCF1 as a Smart Bypass: Fixes the UCF1 motorized
water valve to the open position when the bank is
o and a bypass is required.
REMOTE RESET AND
DEMAND LIMITING SETUP
Remote Setpoint target congurations and Demand
Limiting.
Sensor Input Function: Choose between HMI(None),
Remote Analog Target (Input 6), or BAS Target (0-10).
Sensor Input Type: Choose between 4-20mA or
2-10VDC for Remote Analog Target use.

size as “Not Used.”
Module Size Options are: Not Used, 20 Ton, 30 Ton,
UCF 20/30, 50 Ton, 70 Ton, 85 Ton, UCF 50/70.
If a module is equipped with either a Digital Scroll
compressor or a VFD compressor, the Variable
Capacity check box should be selected.

(timers, variable compressor settings, and more) in
the Compressor Settings Screen.

Use Low Di Press Filter: Prevents ow from dropping
immediately where the decrease in value is limited
by 1 psi every second.
The Minimum/Maximum for the Load (Cold Icon)
and Source (Hot Icon) must be set to match SETRA
DPT dipswitches. The SETRA DPT has multiple
choices for pressure ranges based on the dipswitch.
Example: If the 0-25 psi dipswitch is selected, then
Minimum and Maximum ow must be set to 0 and
25, respectively.
For Reference: Below is the possible SETRA DPT
congurations. The default Range Selection Switch
is D (25psi) and Electrical Output is A (4-20mA) for
general applications.

Calibrate the DPTs while the tubing is connected to
the appropriate piping and the pump is not running.
The pressure dierential should read 0.0. If not, conrm
that the tubing is properly connected, the pumps are
o, the DPT is wired correctly, and there is no air in the
lines. Adjust as needed using the OFFSET elds shown
in the Flow Sensor Conguration Screen.
Example: Flow Sensor Conguration (UCH SHC)
EVAP (LOAD COOL) MINIMUM DPT SENSOR PRESSURE SETPOINT
30 Ton 50 Ton 70 Ton 85 Ton
1.1 PSI 1.3 PSI 1.8 PSI 1.3 PSI
EVAP (LOAD COOL) MINIMUM DPT SENSOR PRESSURE SETPOINT
30 Ton 50 Ton 70 Ton 85 Ton
1.5 PSI 1.8 PSI 2.2 PSI 1.8 PSI
The values in the example are the absolute
minimum for a UCH-style chiller, but can be
set higher. These values are derived from the
respective heat exchanger pressure drops and
the operation limitations table, located in the unit
Installation, Operation, and Maintenance Manual
(IOM). A value of 0.5 psi is added to the result to
accommodate the additional pressure losses of
the piping between the heat exchanger and the
header, where the DPT sensor is located.
MAIN WATER AND AMBIENT TEMPS
Congure appropriate LO/HI Load/Src Water IN/OUT
depending on the brine used in the job site.
Cooling and Heating Low Ambient: Set these values
using the unit IOM.
Enable HP Operation Below: The OAT at which heat
pump operation is enabled.
HI Ambient Temp Unit Disable: Enable the HI Ambient
Limit option for air-source units.
HI Outdoor Air Temp: The OAT at which the air-source
units is disabled.
Use Average Outside Air Temp: Enable this option to
aggregate and average the ambient temperature
from all the modules.

"Trim Chill" causes the trim module to be randomly
selected every time the bank stages up the rst unit
or stages down the last unit.
