NOTE: Installation with underfl oor
heating systems
For underfl oor heating installations,
make sure to install a safety device on
the heating delivery circuit. 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.
ATTENTION:
If the pipes of the heating system do
not have 9l/kW a «system enlarger» is
needed in form of a small buff er in the
return fl ow, just to enlarge the system
volume.
