If the switcher position is „0” does not mean the temperature controller or the ZENIT appliance or a
system which is included these, because the appliance is under voltage
Type of solenoid valve: SIT 845 SIGMA
Method of modulation regulation:
The difference between 3-point control and modulation control is the regulation between two performances limits (from 100% to 50%) is
continuous (there are not any stage) When the thermostat sens th e adjusted temperature minus 3°C degrees than the controler begin
reduce the performance till the temperature of room reach the adjusted temperature. After that the appliance is turn off. The next opera
-
tion begin when the room temperature degrease the adjusted temperature minus 3°C. Than the appliance start with at high performance
(100%) minimum 30 sec� This type of regulation makes it possible to obtain the required temperature in the practically
without any heat fluctuations and to provide economical operation.
Operation method of modulation regulation
At the beginning of its operation, the appliance starts with 100% performance, it is similar to modulation regulation black tube radiant
heater of heating method� When the sensed temperature to 3 ° C approaches the regualtor reduces the voltage to the combustion air
fan� The decreasing the voltage changes the speed of the combustion air fan, changing the total amount of air pressure generated by the
fan� The pressure change of the air supplied is detected by the solenoid valve which is located in the burner head, and according to this
pressure the valve can change the nozzle pressure between maximum and 50% so the gas air ratio during this regulation not changing
Temperature controller type: Only suitable for this control process, modulation temperature controller. (e.g. FP-MOD by Pakole Trade Kft)
