Function
Controlling together with TTC25/TTC40F : TTC has a built-in temperature controller which is connected to control input of TT-S6/D. The analogue output of the step controller is connected to the power control input of TTC which is running together with the step control to aqualize the relay steps. When increased power is required the output to the power control of TTC is increased. When this is at full power the step controller activates the next step. The same fucntion in reverse applies in the event of reduced power requirement.
Controlling from DDC : TT-S6/D can also be controlled by a 0 to 10 V or 10 to 2 V signal from a DDC controller
