TAC 200 is an Outdoor Reset Controller for outdoor reset control of heating systems. It can be used for conventional supply temperature control of mixing valve systems for radiator or floor heating. It can also be used for two or three stage on/off control of gas boilers.With a room sensor, automatic reset of the supply temperature from the room temperature can be obtained. Great flexibility in adjusting the reset curve – a number of curves are available for each individual application –enables optimum matching to the pertinent heating system.
The TAC 200 has high and low limits for the supply temperature. Reading and adjusting values is easy thanks to a display window and push buttons on the front of the controller.Specifications
