Page 3: General Characteristics
The controller has been made using microprocessor techniques with the application of automatic surface assembly process. Owing to the twin part case and revolutionary technical design, the G-202-P00 can be applied to any refrigerated counters or refrigeration chambers. The safe voltage operated control panel (5 V) may be installed in any place, without the necessity of cutting any additional openings or running a number of power supply cables far away from the equipment being controlled. - Page 4 Page 4 Service Manual for Producers SCCB TYPE G-202-P00 The simplest thermostats are equipped with the following: 1000 – compressor 1200 - compressor and lighting system While the mostly developed ones are equipped with the following: 1034 - compressor, fan, heater, ...

For store equipment the SCCB executive module MUST be mounted on the rail set to down towards the floor!!! 3. Any metal elements, through which the G-202-P00 or its cables are run should be ground or protected otherwise. Fitting G-202-P00 to enable direct action of water on it (e.g. water condensating on the bottom cover of the shop window), touching the outlet pipe from the evaporator etc. -

Page 6 Service Manual for Producers SCCB TYPE G-202-P00 9. If heaters are used, their power must be fitted correctly, which means that during failure of the G-202 or of the external contactor and switching them on for good, there were no possibility of fire or the device damage. -
Page 7: Operation Method
7. After every reaching of the preset temperature (user set temperature minus bottom value of the hysteresis), as well as following any power failure or voltage drops below 175 volts, the G-202-P00 will make impossible for the compressor to be activated for the period as specified by the ‘c2’ parameter. If, however, ‘c2’=0min, the protection time will last 60 seconds following any power failure. -
Page 8: B - Defrosting
3. If the defrosting occurs, and the temperature on the evaporator is lower than set in the ‘d2’ parameter, the G-202-P00 will activate the defrosting process, and after reaching the temperature as specified in the ‘d2’ parameter, the unit will enter the defrosting exiting mode (this status is signalled by the green LED, which blinks on the pushbutton). -
