  3.26  SYSTEM SETPOINT CORRECTION FUNCTION

In the presence of hydraulic disconnections on the system which separate the appliance from the low temperature zone (zone 2), a func-
tion can be activated which allows to meet the demands, by correcting the appliance’s setpoint.
The corrections can be made either in heating or cooling mode only.
They are activated by setting the parameters P 23 or P 24 at a value > 0°C.
Following a demand, the correction begins after a time equal to P 21 and continues by 1°C every P 22 minutes.

  3.27  HEATING / COOLING SELECTOR FUNCTION

The type of demand, central heating or cooling, can be selected from the external selector S 44 (see Connections diagram Fig. 8).
To use this command, the function in question must be enabled by means of the parameter A 39=ON.
To make the demand, select the type: central heating = closed contact, and cooling = open contact, and close the contact of zone 1 room 
thermostat.
The remote devices cannot be used when the function is enabled, except for the room thermostat of zone 1; even the demands of other 
zones, 2 or 3, are disabled automatically.

  3.28  DHW  RECIRCULATION  FUNCTION

It is possible to manage DHW recirculation by activating the circulator based on a set schedule (see parameters U 32 and U 33).
The function is activated by selecting the relative function in parameters P 03, P 04 and P 05.
If U 32=U 33, the function is active all day.
For correct operation of recirculation it is necessary to install the relay board (optional kit).
