Thermostat TA3n - household thermostat. Temperature control modes

thermostats Italian company IMIT stamps TA3n and TA2n are used to regulate the temperature in heating systems to maintain the most comfortable temperature indoors, as well as to save electrical energy, going to heating at a time when there are no people in the room. For example, in working time it is necessary to maintain the temperature at least +20°C, and at night it is enough to maintain a temperature of +7°C in the room, which saves half of the electrical energy, and therefore saves half the money for heating every day.

Brand thermostats TA3n are practical temperature control devices that are affordable to the consumer and provide high quality regulation.

Currently thermostats (thermoregulators) TA2n are out of production and replaced by an improved model of the brand TA3n.
From the old model, he inherited ease of use and reliability. The advanced adjustment knob allows you to limit or fix the set temperature. Thermostats TA3n are presented in four modifications, which allow to obtain the most exact match to the needs of the consumer: execution with a signal lamp, with an ON/OFF switch or with a WINTER/SUMMER switch, and also without additional functions.

The operation of the TA3n thermostat is based on the expansion of saturated steam in the gas bellows.
Unlike similar devices, TA3n thermostats are highly reliable, because simple mechanical design is not prone to breakage.
