Operation Manual

Introduction4
An underfloor heating control system can in
principle have 3 different configurations:
• with an evohome controller
• with a central operating device CM927
• without a central operating device
This configuration determines the further
procedure for commissioning and binding.
Underfloor heating control system
with an evohome controller
With the evohome controller each zone can be
controlled separately with an individual time program.
The room setpoint generators/sensors DTS92,
HCW82 or HCF82 as well as the boiler relay BDR91
communicate directly with the evohome controller.
The evohome controller is connected with the underfloor
heating controller, see "Binding the underfloor heating
controller with the evohomecontroller" on Page 15.

Option
Underfloor heating control system with
a central operating device CM927
The central operating device CM927
communicates directly with the underfloor
heating controller HCE80(R)/HCC80(R).
The room setpoint generators/sensors DTS92,
HCW82 or HCF82 as well as the boiler relay BDR91
also communicate directly with the underfloor
heating controller HCE80(R)/HCC80(R).
The operating device CM927 is connected with
the underfloor heating controller, see "Binding
the room device CM927 with the underfloor
heating controller" on Page 16.

Option
Underfloor heating control system
without a central operating device
The room setpoint generators/sensors DTS92,
HCW82 or HCF82 as well as the boiler relay
BDR91 communicate directly with the underfloor
heating controller HCE80(R)/HCC80(R).
Binding with the room device has to be carried
out at the underfloor heating controller HCE80(R)/
HCC80(R), see "Binding the underfloor heating
controller without time program" on Page 17.
