Control configuration  

Identifying the firmware version 

The parameters and functionality of controller depend on its firmware revision. It is therefore important to use a 

matching product version and parameter set. The firmware version is shown on the large LCD digits when pressing UP 

and DOWN buttons for more than 3 seconds simultaneously.  

Control Parameters (Access code: 241) 

Warning! Only experts should change these settings! See user parameters for login procedure.

FC 04 

Economy (unoccupied) Mode temperature shift: 
The comfort (occupied) setpoint is shifted by the value 
set with parameter. If heating is active the comfort 

setpoint will be decreased, if cooling is active, the 

setpoint will be increased. (Enable with UP06.)

function in cooling mode 

0…10.0°C (20.0°F) 

1.0°C (2°F) 

FC 07 

Switching Hysteresis is the difference between switching 

on and switching off. A small hysteresis will increase the 

number of switching cycles and thus the wear on fan and 

relays contacts. 

0…10.0°C (20.0°F)

Mold Protection:  

In mold protection, the fan keeps running independent of 

temperature as long as the unit is switched on.

Dead Zone Span: 
The Dead Zone Span lies between the heating and the 

cooling setpoint. The output is off while the temperature 

is within the dead zone span. A negative dead zone is not 

possible.

Heat/Cool Changeover Delay (if set to FC11 = 3): 
A demand to switch between heating and cooling must 

persist for the length of time set with this parameter 

before the controller switches. Prevents activation of a 

sequence during a short-term change in temperature in 

order to protect equipment (with control overshoot for 

example)
