9 Regulations
This chapter will state all main regulations made by the c-pro CLIMA system.
At the side of the title of every paragraph, in brackets find the control module or modules involved
in these regulations.
It can therefore be immediately understood from which application to set the function and if the
function is available or not in the system available, depending on the presence or not of the control
modules indicated.
9.1 Regulation of the zone temperature
(MCZN, MCCT modules)
9.1.1 Regulation principle
Depending on the system functioning mode (summer or winter) and the time band active in every
zone regulated by the system (manual, economy, comfort in summer and manual, anti-freeze,
economy, comfort in winter), when the temperature detected by the room probe is over (summer) or
below (winter) the active zone set-point value plus the value of the differential for that zone, the
MCZN regulator will activate the corresponding zone heating/cooling manifold.
The activation of the manifold automatically generates an activation request for the delivery
circulation pump in the MCCT controller (delivery line 1 or delivery line 2) that serves the
requesting zone which, after a delay time that can be set from the parameter, activates the
circulation of water in the system and the management of the mixing valve.
After activation of the circulation pump the delivery water temperature control is performed.
Whenever the temperature of the delivery water does not satisfy the delivery set-point (or the
mixing valve set-point, if present) after a delay time that can be set from parameter, the heat
pump/boiler can be activated in winter mode (depending on the settings made) or the chiller is
activated in summer mode.
To regulate the delivery water temperature of the mixing valve and the relative utilities for
heating/cooling of the water, consult the relative paragraphs.
9.1.2 Management of the zone heating/cooling manifolds
(MCZN module)
The zone heating/cooling manifold is activated when:
- Winter functioning mode: the value of the room set-point is lower that the active room set-
point - hysteresis value (differential)
- Summer functioning mode: the value of the room set-point is higher that the active room
set-point + hysteresis value (differential)
Every zone heating/cooling manifold present in the system works independently and, once
activated, generates an activation request of the delivery circulation pump to which it is associated
using the relevant parameter.
