10-1)Heating thermostat operation

When the heating room thermostat is OPEN, the usual heating AUTO operation is performed.

After 30 minutes has passed, if the heating room thermostat continues to be in the OPEN status, the operation raises the water temperature by 1 degree every 30 minutes. The same heater control as that of the usual HP operation applies to the backup heater and booster heater.

When the heating room thermostat is CLOSE, the heat pump performs thermostat off. During the thermostat off, the operation lowers the set water temperature by 1 deg every 30 minutes. When the thermostat off is completed, the backup heater and booster heater stops being energized.

10-2)Cooling thermostat operation

When the cooling room thermostat is CLOSE, the usual cooling operation is performed. (Initial set water temperature 20°C)

After 30 minutes has passed, if the room thermostat continues to be in the OPEN status, the operation lowers the water temperature by 1°C every 30 minutes.

When the cooling room thermostat is OPEN, the heat pump performs thermostat off. During the thermostat off, the operation raises the set water temperature by 1 degree every 30 minutes.

11)Forcible stop control (Option board TCB-PCMO3E is necessary. Connect the connection cable to the water heat exchange board CN210.)

•When CLOSE occurs between "HEAT" and "COM" of TCB-PCM03E, the RED LED on the option board lights and the operation (hot water supply, heating, cooling) stops. To restart the operation, use the operation button of the remote controller.

12)Output signal control 1 (Option board TCB-PCIN3E is necessary. Connect the connection cable to the water heat exchange board CN208.)

•If an error detecting signal is output, CLOSE occurs between the terminal 1 and 2.

•If a boiler output signal is output, CLOSE occurs between the terminal 3 and 4.

•In either signal above is output, the red LED on the Option board lights.

13)Output signal control 2 (Option board TCB-

PCIN3E is necessary. Connect the connection TCB-PCIN3E	PJ20	CN208
cable to the water heat exchange board		Blue
CN209.)

• When defrosting is in operation, CLOSE occurs between the terminal 1 and 2.

• When the compressor is in operation, CLOSE occurs between the terminal 3 and 4.

In either signal above is output, the red LED on the OP board lights.
