(fig. 25)
This contact must be ABSOLUTELY operated by switch or other device that controls
the closing and opening.
Water pump
The water pump must be connected to terminals 26 and N1; with maximum current
consumption of 1A. For higher electrical consumption, it is necessary to use an
appropriate relay. In standard configuration, the microprocessor control switches off
the water pump when the set-point is reached. This solution significantly reduces
power consumption when the set-point is reached or the unit is in stand-by.

Remote control panel
All unit functions can be managed with the remote control panel up to a maximum
distance of 50 metres. The panel must be connected to the unit by means of 2 wires
with section of 0.75 mm2 up to a maximum distance of 50 metres. The power supply
cables must be separated from the remote control panel connection wires, to
prevent interference.
The remote control panel must be connected to terminals 60 - and 61 +. The remote
control panel cannot be installed in areas with high levels of vibration, dirt, humidity
or corrosive agents. Leave adequate clearance around the ventilation apertures.
