GENERAL DESCRIPTION
REGULATION:
The control makes the system regulation as follow:
- Receives the signals of analogue inputs through the inlet and outlet probe temperature values and the refrigerant
piping probe temperature/pression(the probe is placed in the plater/exchanger) two for model Climatic
®
400.
- Receives digital inputs through the status of low and high pressure switches, flow switch (water flow) status and
from electrical protection of fan and compressor.
According to the values and status of analogue and digital inputs manages: the output signals; compressor, fan
and status of water pump operating, obtaining the regulation of the inlet water temperature to the unit, regulating
the speed of the air fan volume, activating the defrost cycle (heat pump units only); output signals water exchange
heater, water tank heater, and hot gas valve (all these elements are an option) used to protect the unit, and also
activates the alarm codes about, setting pressure switches, flow switch, water flow, and the electrical protection
of fan and compressor (see alarm section).
- A group of parameters let the control be programmed for each application.
