Page 5: Method Of Operation
It is not recommended to extend the sensor cable beyond 20 m. THE WAY OF CONNECTING THE SENSOR CABLES TO THE TERMINALS OF THE EXECUTIVE MODULE SENSORS IS ARBITRARY!!! (analogous to the way of inserting a plug into a ~230V contact) for cable extensions we propose to use cable type OMY 2x0.5 mm The connection of the cables in the case of extensions should be made very carefully by soldering each pair of wires and placing heat shrink sleeves over them. - Page 6 1. Evaporator blowdown The thermostat works in the opposite way to the condenser, i.e. an increase in pressure/temperature causes a decrease in blowdown. Blow czas Temperature Parameter Parameter ‘d0’or ‘d2’ or pressure ‘d1’ or ‘d3’ 2. Method of blowing A maximum of 4 fans can be connected to the thermostat, a minimum of 1. The parameters 'r1', 'r2', 'r3' are used to determine which relay the fans are connected to.
- Page 7 4. Alarms Compressor head overheating alarm If parameter 'r5' is set to 1, the compressor head overtemperature alarm is allowed. The parameter 'd7' sets the temperature above which the alarm will occur. The alarm is signalled by the display 'A4'. Temperature sensor failure alarms A failure of sensor 3 (condenser) is signalled by the display 'A1'.

The measured pressure can be calculated from the formula: VII. PROGRAMMING OF SYSTEM PARAMETERS After commissioning and checking the correct operation of the device (the factory default settings are entered), we proceed to enter the system parameters of the G-204. To do that, turn off the device using the button . - Page 9 2. Once the unit has been programmed and put into operation, check the operation of the unit and once again check that the system parameters have been set correctly. 3.
