I. GENERAL CHARACTERISTICS
The Self-contained Control Block, called further G-202-P00 is a modern device, comfortable and easy to
use. 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.
The G-202-P00 has been equipped with two temperature sensors, provides the possibility of
connecting doors opening sensors to the executive module, which are safe voltage operated (5 V), as well as
four outputs allowing direct connecting of the 230 V operated equipment, with loading ability as summarized in
table 1.
At the special request of the Customer, the G-202-P00 may also be equipped with an additional
evaporator frosting detection system, connected to the thermostat, causing the unit to automatically enter the
defrosting mode.
If the G-202-P00 is used in refrigeration devices, it stabilizes the temperature, as well as controls
automatic defrosting, the period of which may be adjusted to specific surrounding parameters; it is also
equipped with a pushbutton for activating manual defrosting. The G-202-P00 has also been equipped with
lighting system switch over that operates independently of the main switch.
No special maintenance measures are required for these thermostats; the keyboard has been made
from the special kind of foil, high temperatures resistant as well as resistant to most chemicals. However,
cleaning this foil with sharp objects is not allowed. Instead, use the damp cloth and clean the front panel with it
from time to time.
