IOM BASIC CLIMATIC CONTROLLER - Page 3
This equipment is an electronic device that controls
packaged water cooling systems.
The thermostat allows the following operations:
- Unit ON/OFF
- Select system operating mode
- Set point adjustment
- Alarm signal relay
- Display temperature
- Status of the unit alarms
- Possibility of remote ON/OFF.
- A remote controller as an option
The control supplied incorporated on the unit contains the
following devices:
REGULATION:
The control makes the system regulation as follow:
- The signals of analogue inputs through the inlet and outlet
temperature and from the refrigerant piping temperature.
- Receives digital inputs through the status of low, high and
pressostat, flow switch (water flow) status and from electrical
protection of fans and compressor.
According to the valves and status of analogue and digital
inputs manages.
The out put signals; compressor, fan and water pump
operating, obtaining the regulation of the inlet water
temperature to the unit, regulating the speed of the air fan
volume, output signals water.
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 pressurestat, flow
switch, water flow, and the electrical protection of fan and
compressor (see alarm section).
- A group of parameters allow the control be programmed
for each application within factory set limitations.
