CAUTION
• The maximum current available from the
booster heater output is 1 A. Do not connect
the booster heater directly to CN23 on the
Hydro Unit. A separate contactor, supplied
locally, must be used to supply the booster
heater.
• The booster heater can be installed only for room
heating and cannot be used for hot water supply.
The booster heater is an external heater, supplied
locally, used to assist the Hydro Unit during low
ambient conditions.
• The AC230 V 1 A output from the Hydro Unit must only
be used to energize an external contactor. (Supplied
locally)
• The output from the Hydro Unit is only enabled when
the outdoor air temperature is less than -20°C.(*)
• Ensure the external booster heater is installed and set
up in accordance with all Local, National and
International regulations.
(*) For HWT-110, it is less than -25°C.
• Connect the external booster heater to the Hydro
Unit in accordance with the diagram shown below.
• Connect the coil, of the field supplied contactor, to
terminals 5 & 6 on CN23. The contactor will energize
in the event of low ambient conditions.
• A separate dedicated electrical supply must be used
for the external booster heater. This must be
connected through the contacts on the field supplied
contactor.
