Installation
1. Mount in a dry and reasonable clean location free of excessive
vibration.
2. Wire in accordance with INNOTECH connection diagrams and
local bylaws or refer to your local distributor.
Wiring
1. Connect 240VAC supply to the correct terminals on the
controller, observing the correct polarity of the connections.
2. Connect the EARTH to the correct terminals on all units.
3. DO NOT connect 240VAC to the control terminals.
4. Ensure that the wiring between the control station and the
controller is correctly connected. Failure to do so will result in
malfunctioning and may damage either or both units.
5. The maximum wire length between the control station and
controller should not exceed 50 metres. The wiring between
these devices should not be run in parallel with conductors
carrying high current.
Digital Inputs
DI1 Timeclock
The Microcontroller is equipped with a remote timeclock enable
function.
When the time clock input (DI1) is "ON", the Microcontroller will run
in A/C mode.
DI2 Aer Hours
The Microcontroller is equipped with an Aer Hours timer.
When a pulse is received on the Aer Hours input (DI2), the unit will
run in A/C mode for the period set in Program Parameter 6.
If a pulse is received while the Microcontroller is in Aer Hours mode,
it will toggle o.
DI3 Unit Disable
The Microcontroller is equipped with an AC Unit Disable function.
If the Disable Input (DI3) is "ON" for the period set in Parameter 7, the
Microcontroller will shut down the air conditioning unit. When the
Microcontroller is disabled, the A/C LED will flash to indicate that it is
being overridden. When the remote disable input is opened, the unit
can be restarted by pressing the A/C button.
DI4 Device Disable
The Microcontroller is equipped with a Heat/Cool disable function.
If the remote disable input (DI4) is "ON" for the period set in
Parameter 9, the Microcontroller will shut down the specified A/C
devices (Heat only, Cool only or Heat and Cool) as indicated in
Parameter 8. If an A/C device is being overridden, the corresponding
Mode LED (Heat/Cool) will flash. When the input is turned o, the
unit will restart the A/C devices as required.
Analogue Outputs
AO1 Hot Water Valve
The Microcontroller is equipped with an output for a hot water valve.
When the Microcontroller is in heating mode, the analogue output
will vary linearly from 0-10V over the range of the Proportional Band
(Parameter 4).
Digital Display
The digital display will show the following error codes to assist with
fault finding.
• Display Reads "99.9"
This indicates either a faulty sensor or faulty sensor
cabling.
• Display Reads "HLP"
This indicates that communication between the Control
Station and Controller is not operating.
First check the interconnecting cabling and if this is OK, contact your
local Innotech Distributor for assistance.
Adjustable Parameters
Jumper Settings on the Control Station
Jumper #1 (JP1 Rev)
Not Used.
Jumper #2 (JP2 H/C)
Not Used.
Jumper #3 (JP3 Fan)
This jumper is used to select continuous fan operation or fan cycles
with heating.
When the link is closed, the fan runs continuously on cooling and
cycles with heating.
Program Functions on the Control Station
All variable settings for the Microcontroller are adjusted at the
Control Station.
Programming Mode
To enter Programming Mode, depress and hold the and
buttons for 5 seconds. The display will become blank indicating that
you are in the Programming Mode. Release both keys and the display
will show parameter 0.
While in the programming mode, the following buttons are active:
Change to the next parameter
Increase the current parameter value
Decrease the current parameter value
To Exit the Programming Mode, depress the and buttons
and the new setting will be saved.
This product should only be installed by qualified personnel.

Parameter 0 - Sensor Calibration
The Display will show the sensor temperature. To oset the
sensor temperature, adjust using the or buttons.
• The range of the Oset is ± 9.9°C
• The factory default setting is 0.0°C
Parameter 1 - Minimum Setpoint
The display will show the Minimum Setpoint to which the
controller can be set.
• The range of the Minimum Setpoint is 0 to 99°C
• The factory default setting is 15°C
Parameter 2 - Maximum Setpoint
The display will show the Maximum Setpoint to which the
controller can be set.
• The range of the Maximum Setpoint is 0 to 99°C
• The factory default setting is 30°C
Parameter 3 - Dead Band
The display will show the Dead Band setting.
• The range of the Dead Band is 0 to 9.9°C
• The factory default is 1.0°C
Parameter 4 - Proportional Band
The display will show the Proportional Band (PB) setting. A PB
setting of 2°C will result in a dierential of 2°C for heating and 2°C
for cooling.
• The range of the Proportional Band is 0 to 9.9°C
• The factory default is 1.0°C
Parameter 5 - Fan Run On Time
The display will show the Fan Run On Time.
This is the period that fan will run for if it is operating in heating
mode and the controller is turned o. This is to remove any
residual heat where electric heating is used.
• The range of the Run On Time is 0 to 99 seconds.
• The factory default setting is 30 seconds.
Parameter 6 - Aer Hours Timer
The display will show the Aer Hours Time.

received.
• The range of the Aer Hours Time is 0 to 9.9 hours.
• The factory default setting is 1 hour.
Parameter 7 - Unit Disable Timer
The display will show the Unit Disable Time.
This is the time that the controller must see the Unit Disable
input for before it turns o.
• The range of the Disable Timer is 0 to 99 minutes.
• The factory default setting is 1 minute.
Parameter 8 - Devices Disable
The display will show 4 settings of device disable.
• 0 - None, 1 - Heat, 2 - Cool, 3 - Heat and Cool
• The factory default setting is 3 - Heat and Cool.
Parameter 9 - Device Disable Timer
The display will show the Device Disable Time. This is the time that the

• The factory default setting is 0 seconds.
Timer Function
The button when pressed will display the time in which the unit
will change state. For example: if the unit is o, the unit will display the
time till the unit will turn on. If the unit is on, it will display the time till it
will turn o.
Continuously pressing the button will increase this time by 10 minutes
until it reaches 24 hours, when it will then roll over and display the
minimum time adjustment. The time is adjustable from 10 minutes to
24 hours. If le for 5 seconds, the display will revert to displaying the
sensed temperature.
Mode Function
The button will switch between Auto, Heat and Cool modes.
In Auto mode, the unit will heat and cool as required to maintain the
setpoint conditions.
In heat mode, the cooling is disabled and the unit can only heat to
maintain set point conditions (winter mode).
In cool mode, the heating is disabled and the unit can only cool to
maintain conditions (summer mode).
Start Up Default Settings
The Microcontroller can be set to start in any mode of operation.
To set the start up default, adjust the Microcontroller to the desired
settings and then press and hold the and buttons for 5
seconds.
The display will become blank indicating that the new settings are
saved.
