APPENDIX
This section introduces variation of various systems using Air-To-Water Heatpump and actual setting method.
(NOTE) : For this model, both external room thermistor of Zone 1 and external room thermostat of Zone 1 must always be connected to main
indoor PCB only regardless of Optional PCB (CZ-NS5P) connection.
1-1 Introduce application related to temperature setting.
Temperature setting variation for heating
1. Remote Controller
Floor heating
Indoor
Outdoor
Connect fl oor heating or radiator directly to the Tank Unit.
Remote controller is installed on Tank Unit.
This is the basic form of the most simple system.
2. Room Thermostat
Outdoor
Tank Unit receive Room Thermo signal (ON/OFF) from Remote controller
to control HP and circulation pump.
There is a build-in thermistor in the remote controller.
Floor heating
Indoor
Connect fl oor heating or radiator directly to the Tank Unit.
Remove remote controller from Tank Unit and install it in the room where fl oor heating is installed.
This is an application that uses remote controller as Room Thermostat.
3. External Room Thermostat
Outdoor
Room
Thermostat
(Field supply)
Floor heating
Indoor
Connect fl oor heating or radiator directly to Tank Unit.
Remote controller is installed on Tank Unit.
Install separate external Room Thermostat (fi eld supply) in the room where fl oor heating is installed.
This is an application that uses external Room Thermostat.
