FIELD: household thermal regulators household thermal regulators production. SUBSTANCE: household thermal regulator - apparatus for automated keeping of given temperature in premises or storages - has control circuit composed of in series connected resistor, diode, temperature sensor - thremocontactor and normally closed tumbler of control and also executive circuit composed of in series connected to each other and with loading - heating members of electrical switch-thyristor and alert lamp (or sound device). Executive circuit control is exercised by feeding to control lead of thyristor signal from point of diode and thermocontactor connection. During thermocontactor control circuit break caused by decrease of temperature in storage below threshold temperature or during imitation of the situation by control tumbler turned off, key-thyristor is opening and network voltage is fed to loading, that is testified by electric bulb lighting up (or sound signal switches on). The advantage to check the whole device serviceability at once increases its reliability. EFFECT: increased reliability of regulator. |
