THERMASREG
Mechanical temperature controllers ⁄ contact thermostats THERMASREG
controlling and limitation of temperatures at pipes or vessels, e.g. in connection with hot-water or floor heating systems. The contact temperature
controller ALTR is built as one - step device, as adjustable temperature controller TR (with external setting) or as adjustable temperature monitor
TW (with internal setting).

Heating: The preset setpoint (scale value) is equivalent to the switch-off value of the heating.
The switch-on value is lower by the amount of operating difference.
Contact 2 - 3 breaks when temperature rises to the preset value.
Cooling: The preset setpoint (scale value) is equivalent to the switch-on value of the cooling.
The switch-off value is lower by the amount of operating difference.
Contact 1 - 2 closes when temperature rises to the preset value.
