Warning
Never attempt to switch the heater on or off by connecting the room thermostat (or other control devices) to
the electrical power line.
5.2.3 Connection to climate control system
The space heater has been set up for connection to a remote climate control system:
therefore, the heating function (button A), the ventilation function (button B), the
voltage warning lamp signal display (lamp E) and the reset button warning lamp (lamp
D) can all be managed.
Warning
It is possible to display only the block signal and not manage the reset button
function (D).
The manual reset function must always be used only and exclusively after
having understood the reason for the safety lockout.
The electrical connection must be made using the 9-element terminal block on the
upper part of the electronic connection board. Use only interconnection relays (not
supplied with the heater) with electrical specifications (voltage and frequency)
compatible with those of the available climate system.
