TA 200 Reset Controller
TA 200 is an Outdoor Reset Controller for outdoor reset control of heating
systems. It can be used for conventional supply temperature control of mix-
ing 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 TA 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.
