To enable this function, the external air temperature probe must be enabled
8.19.7 Cooling/Heating Function by Request
If enabled in the Enablement Control by Request PC80 parameter, this function requires a specific temperature probe, remote
(generally located in a storage tank): upon reaching of a specific setpoint (in the cooling function the Summer Control by Request
Setpoint PC81, in the heating function the Winter Control by Request Setpoint PC82) and after a Control by RequestDelay PC85
determines activation of the circulation pump and the compressor to perform the function requested with classic temperature regulation
selected (regulation of the return or supply temperature). The unit switches off when the storage tank is “satisfied”, that is, once the
Summer Control by Request Setpoint PC81 – Summer Control by Request Differential PC83 (if cooling) or the Winter Control by
Request Setpoint PC82 + Winter Control by Request Differential PC84 (if heating) have been reached.
To use this function you need to enable the auxiliary regulation probe in the HAxx parameters.
8.19.8 Setpoint variation from digital input
You can change the working setpoint by using a digital input. To use this function, set the offsets of the setpoint in parameters PUC1
(summer operation) and PUH1 (winter operation).
It is also necessary to configure the digital input to be used by configuring the HBxx parameters.
8.20 Management of the EVDRIVE03 built into the system
Management of the electronic valve must be optimised and not be limited to a typical superheating control.
There are various conditions and rules which must take into account other variables of the system on the whole as well as variables
concerning superheating (evaporation temperature and pressure) in order to limit problems due to delays introduced by the
temperature probe itself and its positioning. These functions must be enabled in the parameters so that the manufacturer may exclude
them.
8.20.1 Enablement of EEV Operation
The controller knows when it’s time to activate the unit (turn on a compressor) and consequently must enable the operation of the
EVDRIVE 03 driver via CAN bus.
