NOTE: Installation with under-floor systems
For under-floor installations, make sure to install a safety device on the heating delivery circuit, as required by DTU 65.11. For the ther-
mostat 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-floor heating thermostat open”. The system will start again when the manual re-arm thermostat is
closed.
