Installation
Mounting on electric box
1. Separate back plate from the controller by loosing the cover screw;
2. Align the mounting holes on the screw holes of the electric box(applicable to 65x65 or US standard box);
3. Fix the back plate on the electric box by tightening the back plate screws. Suggest to use Philips wider “truss head” or
“washer head” #6-32x 3/4”(20mm).
4. DO NOT let the bolt head rise above the wall of mounting holes of back plate. It might cause the short circuit of the
controller.
Mounting front cover
1. Lock front cover on the back plate by tightening the cover screw underneath with screw driver of Philip electronic
instrument type or similar.
Wiring Example
1. All wires come from electric box must be inserted above the retainers of respective terminal block before
tightening the captive screws;

� Unoccupied Set Points: activated by occupancy contact; Cooling: 28.0℃/ Heating: 15.0℃
� When schedules are activated, refer to cooling/ heating set points according to current
schedule.
� When pause or stop schedules, refer to manual set point or latest set point as Cooling Set
Point and dead band for Heating Set Point deviation.
� Scheduled Cooling Set Point range: 10.0℃ ~ 37.0℃; Heating Set Point range: 4.5℃ ~ 32.0
℃; make sure to set heating lower than cooling set point to have proper controls.

Control Actions
There are two types of heating control output: Modulating (0~10 VDC) and On/ Off (SPDT
relay). Both will output simultaneously.
1. Modulating Type Heating Control:
(1) Output Voltage: Valve output allow minimum adjustment (AO1 Low(E5)) from 0-2 Vdc and maximum
adjustment (AO1 High(E6)) from 8 to 10 Vdc. These two output voltages can be gauged by multimeter during
setting to reflect the setting change effects.
(2) Reverse Output: The output voltage can be reversed by setting rE-H(E18) to 0(Direct) or 1(Reverse).
(2) When Demand for Heating, a “Running ( Gear) ( )” icon will be shown on the LCD.

requirement. On Demand for Heat Terminal 3 will = 24Vac On/ Off differential can be set at (dIFF(E19)).

Special:
1. ESI (Energy Saving Input) Contact status -- When the contact is activated (Room unoccupied), a “Moon ( )”
icon will be shown on the LCD and the thermostat will change the set-point temperatures of Cooling & Heating
to be ESIC & ESIH (refer to Engineer table for details.). When the contact is deactivated (Room back to be
occupied), it will set the set-point values back as normal.
2. If disable local ESI contact detection, the room will become always occupied status as default.
3. The icon , , , or will be shown on LCD while the Schedule 1,2,3, or 4 is running or being
set.
4. If press “MODE” button, there are three schedule modes “RUN, HALT, and STOP” for selection.
a.) RUN mode means activating Schedules. And at the same time an icon ( ~ ) will be steadily shown
on the LCD.
b.) HALT mode means temporarily pause current schedule and using manual S.P instead. And the icon
( ~ ) will be flashing on the LCD.

c.) STOP mode means stop to use manual S.P until manually activate schedule again. And the icon

Engineer Mode Operation
This mode is highly suggested to be operated by trained engineers because it is related to system parameters that
will affect the control results. To operate:
1. Press “Up” and “Down” buttons for over 5 seconds to enter into engineer mode;
2. Press UP or DOWN button to rotate the menu item and press MODE button to enter into the item;
3. Press UP or DOWN button to change the setting and press MODE button to confirm the setting and return to
menu item selection. For no button pressed for 10 seconds, it will go back to menu item selection. The setting
won’t be changed then.
4. To leave Engineer Mode, rotate till “End” and press MODE button or leave the button intact for 10 seconds.
