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/cooling modes, and the remote control will
report error code 116 “Under-fl oor heating thermostat open”. The system will start again when the manual re-arm thermostat is closed.
