Following the principles of operation of the various hydraulic diagrams.
Important considerations:
•
healthcare will always have priority
•
There are three types of stand-by:
Type 01
: the ambient temperature detected by the probe on the board has reached the SET AIR set
Type 02:
the water temperature in the boiler has reached the SET H2O set
Type 03:
the external thermostat has detected that the desired temperature has been reached and therefore the
contact is open.
In this specific case the boiler behaves as follows:
If the thermostat carries voltage to the card causing faults, the warranty will expire.
To configure the thermostat, simply remove the jumper on the THERM terminal (see the tab on page 16) and connect our
