USE OF SOCKET [P]
• If the circulation pump must be controlled for both the heating function
and the cooling function and the two functions will use the same pump,
insert confi gurator 1 in [P]. Then connect the pump to an actuator
confi gured in zone 00 ([ZA] = 0, [ZB] = 0) and put confi gurator 1 in socket
[N] (see actuator confi guration).
• If a pump must be controlled for the heating function only, insert
confi gurator 2 in socket [P] and connect the pump to an actuator
confi gured in zone 00 with [N] = 1 (see actuator confi guration).
• If a pump must be controlled for the cooling function only, insert
confi gurator 3 in socket [P] and connect the pump to an actuator
confi gured in zone 00 with [N] = 2 (see actuator confi guration).
• If two separate pumps must be controlled, one for the heating function
and one for the cooling function, insert confi gurator 4 in [P]. Then connect
the heating pump to an actuator confi gured in zone 00 with [N] = 1 and
the cooling pump to an actuator confi gured in zone 00 with [N] = 2 (see
actuator confi guration).
PUMP SWITCHING ON DELAY
When the system has a circulation pump managed by the Temperature
control function, it may be necessary to insert a confi gurator in the [DEL]
socket of the temperature sensor as well. This operation is only performed
if the pump is to switch on with a certain delay after the zone valves open.
This choice depends on the type of valve installed and allows switching on
the pump only when the valve is completely open.
Insert the confi gurator corresponding to the delay required in the [DEL]
socket.
In this case the number shown on the confi gurator indicates the time in
minutes.
If confi gurator 3 is inserted in [DEL], after closing the relay which commands
valve opening, the sensor waits for 3 minutes before switching on the pump.
A delay of a maximum of nine minutes can be confi gured, depending on the
time the valves need to open. Refer to the technical specifi cations declared
by the solenoid valve manufacturer to fi nd out the opening time.
Configuration of socket [P] for
a system with one circulation
pump for the two heating and
cooling functions.
Configuration of socket [P] for
a system with one circulation
pump for just the heating
function.
Configuration of socket [P] for
a system with one circulation
pump for just the cooling
function.
Configuration of socket [P] for
a system with two separate
pumps one for heating and one
for cooling.
