"GAZDA" G352-25 is the temperature regulator controller ensuring completely automatic functioning of two different coppers of system of heating and providing with hot water at the greatest possible profitability, reliability and safety.
It is intended for installation in control units of electric boilers: 1-phase - to 5,5 kW or 3-phase to 16,5 kW.
The original operating program, digital sensors, complete set of the operating input and output devices, devices of visual control of the parameters and their programming united in one compact case – provide a possibility of creation of systems of the most various configurations and difficulties.
Main characteristics and functionality:
1. Interdependent management of two coppers: electric - through the contactor 25A, and gas/solid propellant.
2. Management of two systems of circulation of the heat carrier (two pumps, or the pump and the electrovalve) with installation of different temperatures (for example, heating + 50ºС, hot water +70ºС).
3. The programmable daily timer with real time clock – you install what copper and in what time of day should work (5 programs) – for use of reduced rates for energy carriers.
4. The electronic ampermeter with sverkhbystry protection and function of self-return:
- you always see real current of consumption of the electric boiler;
- at power surges in network or emergence of other reasons of increase in current the copper immediately (0,1 seconds) will be disconnected, but not irrevocably as in a case with the automatic switch – in 5 seconds the system will resume work with earlier set parameters.
5. The operating entrance for connection of external devices (for example, the room thermostat).
6. The Antizamerzaniye function - irrespective of the temperature parameters set by you system will not allow decrease in temperature below +5ºС.
7. The Winter/summer function - choosing the Summer mode, you block system of heating, - but have hot water.
8. Non-volatile memory of the microcontroller (your settings and programs of work remain after any shutdowns). Maintenance of the exact course of hours – the "computer" SR2032 battery (the minimum resource – 5 years).
9. Digital temperature regulators with wide limits of installation of temperatures and hysteresises of inclusion. Sensors – DS18B20.
10. Working capacity at fluctuations of the feeding voltage from 130 to 280 Volts.
11. Bystry and effective protection: both from external emergencies, and from incorrect programming by the user.
The case – on a DIN lath, takes 4 modular places (width of 70 mm).
