• Change-over (heating/cooling switch):
- Instead of the temperature sensor, a potential-
GB
free external contact (not supplied) can be
connected, the closing of which causes the
thermostat to switch to cooling mode and the
I
opening causes it to switch to heating mode.
- The same contact can control up to ten controls
E by connecting the sensor inputs (B2-M) of the
various thermostats in parallel.
- Important:
D
- The 230V power supply of the controls
connected in this manner must come from the same source. The polarities must be strictly respected.
- Maximum total connection length: 80m with 1.5 mm
- As the sensor inputs are connected to 230V, use a contact and cable which satisfy the corresponding
insulation requirements.
- To avoid electromagnetic disturbance, do not route this connection next to power cables.
• Mode switch Eco/Stand-by:
- The same external contact (not supplied) can
control up to ten commands by connecting the
corresponding inputs in parallel. (D1 - GND).
- Important:
- The 230V power supply of the controls

5 - STARTING

Before doing any work on the installation, make sure it is switched off and put out of bounds.

5.1 - PRELIMINARY CHECKS

• Make sure:
- that the water circulates correctly in the air handler,
- that the heat exchanger has been purged,
- that the connections are correctly tightened and have good thermal insulation,
- that there are no leaks,
- that the air handler is well fixed,
- that the power cables are well fixed to their connection terminals,
- that the electric cables are properly insulated from any pieces of sheet or metal parts which could damage them,
- that the unit is connected to earth,
- that no tools or any other objects have been left in the units (specially form packing-pieces in the discharge louvers),
- that the filter is correctly fitted,
- that the condensate discharge outlet is correctly connected,
- that the condensate collection tank is clean.
