MENU > FOR SERVICEMAN > TEMP. TYPE SETTING 
 
The  TEMP.  TYPE  SETTING  is  used  for  selecting  whether  the  water  flow 
temperature  or  room  temperature  is  used  to  control  the  ON/OFF  of  the  heat 
pump. 
 
When  ROOM  TEMP.  is  enabled,  the  target  water  flow  temperature  will  be 
calculated from climate-related curves (refer to “9 Climate related curves”). 
 
For installations  without  room thermostats, space heating  and  cooling modes can  be  controlled  in one of two different 
ways: 
  according to the M thermal Mono’s leaving water temperature alone 
  according to the room temperature detected by the M thermal Split user interface’s built-in temperature sensor alone 
 
WATER  FLOW  TEMP.  sets  whether  space  heating/cooling  modes  are 
controlled according to the M thermal Mono’s leaving water temperature. If 
YES  is  selected,  the  user  is  able  to set  the  M  thermal Mono  unit’s  leaving 
water temperature set temperature on the user interface’s main screen. 
 
 
ROOM  TEMP.  sets  whether  space  heating/cooling  modes  are  controlled 
according to  the room  temperature detected by the temperature  sensor in 
the M thermal Mono user interface. If YES is selected, the user is able to set 
the  room  temperature  set  temperature  on  the  user  interface’s  main  screen,  no 
matter what is the setting of WATER FLOW TEMP. 
 
 
DOUBLE ZONE sets whether there are two zones. 
If set WATER FLOW TEMP. and ROOM TEMP. to YES, meanwhile set DOUBLE ZONE 
to NON or YES, the following pages 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.)

(Double zone is effective) 
If set DOUBLE ZONE to YES and set ROOM TEMP. to NON, meanwhile set WATER FLOW TEMP. to YES or NON, the following 
pages will be displayed. In this case, the setting value of zone 1 is T1S, the setting value of zone 2 is T1S2.
