Heating Controllers
TA 200 OPT
Heating Compensator and
Optimizer
TAC 200 OTP is a heating compensator complete with optimizer control
of the boiler. 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
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. TAC 200 OTP
has high and low limits for the supply water temperature.
The controller has a built-in safety function with three stages of frost protec-
tion. Reading and adjusting values is easy thanks to a display window and
push buttons on the front of the controller.
