Question

There is two thermostat in the same room. One thermostat controls the air temperature of one room while the other controls the temperature for multiple room. The second thermostat needs to stay at the same temperature. If the controller has a three-point system, which are cool, off, and heat, what will be the control action should be expected in the summer and in the winter?

Answer 1

contoller has three point system.

During the summer season when there is need of air conditioning, set first thermostat to the "COOL" position. This tells the controller what to do as temperature rises above the second thermostat setting (turn on the air conditioning system) or when room temperature falls below the second thermostat set temperature (turn off the air conditioner).

During the winter season, when there will need warmth, set the first thermostate switch to the "HEAT" position. This tells the controller what to do when temperatures fall (turn on the heating system) or when temperatures rise to the thermostat setting (turn off the heating system) with respect to the second thermostat.

and second thermostat will be connected at OFF position everytime .
