If set DOUBLE ZONE and ROOM TEMP. to YES, meanwhile set WATER FLOW TEMP. to YES or NON, the following page will 
be displayed. In this case, the setting value of zone 1 is T1S, the setting value of zone 2 is TS (The corresponding TIS2 is 
calculated according to the climate related curves.)

As  an  alternative  to  controlling  space  heating/cooling  modes  according  the  M 
thermal  Mono  unit’s  leaving  water  temperature  and/or  the  room  temperature 
detected  by  the  temperature  sensor  in  the  M  thermal  Mono  user  interface, 
separate  room  thermostat  can  be  installed  and  used  to  control  space 
heating/cooling modes. 
 
In ROOM THERMOSTAT the following parameters should be set. 
 
ROOM THERMOSTAT sets whether or not room thermostats are installed. For installations with room thermostats, select 
YES. For installations without room thermostats, select NON. 
ROOM THERMOSTAT = NON: No room thermostat. 
ROOM THERMOSTAT = MODE SET: Room thermostat can control heating and cooling individually. 
ROOM THERMOSTAT=ONE ZONE: Room thermostat provides the switch signal to unit. 
ROOM THERMOSTAT=DOUBLE ZONE: Indoor unit is connected with two room thermostat.
