Operation Modes 

 

Comfort

: The unit is in full operation mode. All the control functions are operating according to their setpoints. 

The unit displays occupied mode.  

 

Standby

: The set points are shifted according to parameters 

1L00

 or 

2L00

. The heating parameter is shifted 

down and cooling parameter up. The unit displays unoccupied mode. Outputs are limited to 

OP04

 standby 

maximum. For two stages heating or cooling the second stage will not operate while in standby mode. Standby 
operation may be disabled with 

UP06

.  

 

Energy Hold-Off (EHO)

: The unit is turned off, and "Off" is displayed. However, the inputs are still monitored and 

the alarm functions will operate normally. 

Activation of operation modes
