12.2 MANAGEMENT OF SECONDARY CIRCULATOR/BOOSTER PUMP (WITH ROOM THER-
MOSTAT)
It allows the management of a secondary or booster circulator to serve the plant.
A room thermostat (N.C.) must be configured appropriately.
- Thermostat closed contact -> The secondary circulator is activated;
- Thermostat open contact -> The secondary circulator is off with a delay given by P02 (post-pumping).

The temperature control of the Heat pump is independent from the thermostat call.
When the Heat pump is Off, the booster circulator will be off regardless of the thermostat call.

MIXER VALVE MANAGEMENT
The mixer valve is regulated by means of specific PID which strives to maintain the delivery temperature of the radiant panel at the set value.

12.3.1 Determination of setpoint
The setpoint on which to perform regulation is given by
rCO
or
rHE
respectively in cooling and heating mode. If dynamic compensation of the
setpoint is enabled (
b08
=1), then the setpoint will be corrected the same way as the heat pump/chiller.
The maximum and minimum value reached by the compensation are not controlled. Therefore the parameters must be configured so that the
setpoints are not brought to unwanted values outside of the allowed work ranges.
12.3.2
Radiant panels circuit pump
The radiant panels circuit pump is activated when there is a thermostat call and switches off with a delay of
P02
from when the thermostat call
ceases.
12.3.3
Mixer valve
The mixer valve is regulated by means of specific PID which strives to maintain the delivery temperature of the radiant panel at the setpoint
value.
To manage the contact valve, there is a positioning phase at “0”, the output
DO1E
is active until the all open limit switch is reached, time defined
by
i01
(140 seconds).
When
i01
seconds have elapsed, the output
DO 1E
is deactivated. Then the valve goes to the recirculation position, activating output
DO 2E
for
a limit switch closing time
i01
.
When
i01
seconds have elapsed, the output
DO 2E
is deactivated. Then the valve goes to the regulation position, which is corrected every
i02
(10 seconds).
When complete closure is requested, the output
DO 2E
is activated for a time equal to 20% of
i01
to guarantee complete closure and to eliminate
any positioning errors accumulated over time.
