Room thermostat (ON/OFF - HEAT/COOL by digital input)

☞
NOTE
The ROOM THERMOSTAT submenu allows you to set the unit operation based on the status of digital inputs on the
unit's control board.
To set the ROOM THERMOSTAT, go to MENU> FOR SERVICEMAN> ROOM THERMO-
STAT. Press OK. The following page is displayed:
If you want to connect a room thermostat (or a remote switch) for the activation and turning off the unit, ROOM THERMOSTAT
must be set to YES and the MODE SETTING must be set to NON. With this setting, the unit will operate in the mode set as a user
interface only when the thermostat closes the contact.
If you want to connect instead a double contact thermostat (or 2 remote switches) to determine the activation of the unit in HEAT
or COOL, ROOM THERMOSTAT must be set to YES and the MODE SETTING must be set to YES. With this setting, the unit will
operate in the mode required by the thermostat (or by one of two remote switches) and therefore will not be possible to activate the
unit nor to change the operation mode through the user interface.
If you set the unit to be activated via digital inputs the timer function and weekly scedule are not available;
The temperature adjustment can be performed from the user interface.

NOTE
"DUAL ROOM THERMOSTAT" must not be used: set to NON.
NOTE: The setting in the user interface MUST match the thermostat wiring (or remote switches). For more information also see
