GSM
rele
4
. With two power outputs are controlled two electrical appliances such as heating and boiler with contactors, digital inputs detect voltage on
switching / opening a door contact and two analog inputs T5, T6 measure temperatures.
The schematics calculate with usage of the “Load Management Signal”. Logic input No. 1 is activated by supplying an external 12V DC logic input and input 2 uses internal 4V DC
and connects directly to the terminal door contact. The 2 analog inputs T5, T6 connect the temperature sensors. Outputs of the
GSM
rele

control contactors of heater and boiler.
