Heating circuit 2 (or zone 2) (if present)
This circuit (or zone) is preconfigured to be inactive; if present, it
must be activated by adding a jumper or external request signal
(e.g. zone thermostat or thermostat timer), as described in figure
3.9
p. 25.
Once activated, the preconfigured settings are those given in
Table 5.2
p. 32.

5.1.3
Selecting the operating mode and time
programming
The operating mode can be set separately for the heating cir-
cuits/zones as described in the two previous paragraphs. The
following settings are available:
▶
Automatic: the circuit (or zone) works with the Comfort or
Reduced room setpoint, depending on the time program-
ming.
▶
Comfort: the circuit (or zone) works with the room setpoint
set to Comfort.
This setting forces the heating service to run even when
the system is in summer mode.
▶
Reduced: the circuit (or zone) works with the room setpoint
set to Reduced.
▶
Protection: the circuit (or zone) works with the room set-
point set to Protection (anti-icing).
If you select Automatic mode, the preconfigured time program-
ming includes a daily time period in which the Comfort setpoint
applies, from 6:00 to 22:00. Proceed as follows to change this
setting.
For heating circuit 1
1� Access the
End user
menu level, then the Time prog heat-
ing/cooling1 menu.
2� Select parameter 500 (Preselection) and set it to the desired
value. The value indicates the days of the week for which the
following programming operations will apply; the available
values are:
Mo – Su to set all days of the week to the same set-
tings
Mo - Fr to set all working days to the same settings
Sa - Su to set the weekend days to the same settings
Mo, Tu, We, Th, Fr, Sa, Su to program the days indi-
vidually
3� Set some or all of parameters 501 (1st period On), 502 (1st
period Off), 503 (2nd period On), 504 (2nd period Off),
505 (3rd period On), 506 (3rd period Off) to program up
to three time periods to the Comfort setpoint.
You can also copy all types of programming, excepting
Mo - Su, to specific days of the week, using parameter
515 (Copy).
For heating circuit 2
1� In the same way, use menu Time prog heating/cooling 2; in
this case the parameters are 520 (Preselection), 521 – 526
(periods) and 535 (Copy).
The operating mode and the comfort setpoint can easily
be modified at a later time by the end user, if he so
wishes. See the User manual for details.
5.1.4
Setting the heating curve slope and min/max
outlet water setpoints
To set the heating curve slope for a heating circuit, refer to fig.
5.1
p. 33 and select the curve that passes through the circuit's
design point (water outlet setpoint required at the minimum
outside design temperature, with reference to the room temper-
ature setpoint 20 °C).
For example, if the minimum outside design temperature is – 5
°C and the circuit requires a water outlet temperature in these
conditions of 55 °C to maintain a 20 °C room temperature, set
the slope to 1�5.
