Room or return-air sensor connection (option) or inlet sensor
–
Connecting cable, refer to top note on Page 76.
Pos. 1:
Room or return-air sensor
Pos. 2:
Inlet temperature sensor
•
Connect the sensors in accordance with the wiring diagram.
Return-air sensor:
–
When connecting a return-air sensor, set parameter 4: SEL0 = 16 and SEL1 =
auto (continuous fan operation).
–
For wiring a factory-mounted return-air sensor, connect relevant CET terminals
with the corresponding terminals in the unit terminal box (refer to the unit con-
nection diagram for terminals).
Inlet temperature sensor:
–
Installation of inlet sensor in supply line
–
Fixation of sensor with an enclosed clip on the pipe. The clip is suitable for pipe
sizes of 15 mm.
–
Following sensor installation, restore the pipe insulation.

Room sensor:
–
Opening of room sensor casing as illustrated.
–
Fix the casing (see Fig. 6-47) in a suitable place (see Fig. 6-48) using relevant
screws (max. M4).
–
Connect the room temperature sensor according to the wiring diagram (see
Chapter 6.13.1).
–
Close the casing in the reverse order to the opening procedure.
