NOTE: Installation with under-fl oor systems
For under-fl oor installations, make sure to install a safety device on the heating delivery circuit, as required by DTU 65.11.
For the thermostat hookup, refer to “Electrical connections”.
If the delivery temperature is too high, the system stops in both domestic hot water and heating modes, and the remote
control will report error code 936 “Under-fl oor heating thermostat open”. The system will start again when the manual
re-arm thermostat is closed.
