8.1.6 "Heating/cooling integration" function (MCZN modules)
You can activate the "auxiliary heating/cooling" (also referred to by the term "booster").
This function allows the use of the battery housed in the dehumidifier for adjustment of temperature, through an air
system in support of that regularly checked by the system. This function is used to compensate for the transient
adjustment in steps of first heating up or adjustment conditions for switching between very distant from each other.
The auxiliary heating/cooling may be summer or winter, and is defined as a delta from setpoint work environment.
When the ambient temperature is above/below the temperature setpoint of the delta value for a continuous time
defined by parameter, then you will be given the activation of the booster hot/cold.
Should be set to the dependence of integration or booster by one or more zones by assigning the function from
specific parameter maintainer.
The setting is separate for hot and cold booster in order to be flexible to accommodate the adjustment of the set
temperature in the different zones.
8.2 Regulation of the delivery temperature (MCCT modules)
8.2.1 Management of the delivery circulation pumps (MCCT module)
The controller of thermal power station is able to handle up to 6 delivery lines, each with the corresponding circulation
pump.
As previously mentioned, each controlled area should be associated with the discharge line from which it is served.
Through the appropriate parameter circulation pumps can be operated in the following way:
- CONTINUOUS: the circulation pump discharge will remain continuously active system with ON and
no alarms blockers.
- REQUEST FOR TEMPERATURE: the circulation pump discharge will be activated at the request of at least one
of the manifolds heating/cooling zone associated with the discharge line itself.
The activation / deactivation of circulating pumps will follow the timing delay at power on / off established through the
appropriate parameters.
In addition to the demand from collectors for heating / cooling zone, the circulation pumps discharge will be activated
for the following special cycles:
- Protection of low temperature flow line
- Frost protection system
- Cycle anti-grip
The correct functioning of the circulation pumps is controlled via a digital input that can be configured as pump
protection input (block) or delivery flow switch (consult the relative explanatory paragraph).
8.2.2 Management of the utilities set-up for heating delivery water:
boiler (and heat pump (MCCT module)
During winter regulation, once the water has been put into circulation in the system, whenever the delivery work set-
point is not satisfied, the c-pro 3 CLIMA sistema will send a request to the thermal power plant controller for the
activation of the utilities set-up for heating of the delivery water.
The request will remain active until the satisfaction of the set point or stays open until the mixing valve (selected by
parameter PL05 ). If PL05 = 0 , the demand for hot/cold is deactivated to the achievement of the set flow; PL05 if = 1,
the demand for hot/cold is switched off with a delay defined by parameter PL06, complete closure of the mixing valve.
The regulator of central heat MCCT is able to control two different utilities for heating water flow : heat pump and a
water heater.
Depending on the type of system the two utilities of heating may be present separately or simultaneously and will be
handled in the following way:
