Data Sheet for Product

Function
When the adjustable setpoint of the control thermostat (RAZ-TR..) is reached on rising
temperature, contact connection 1-2 changes over to contact connection 1-4. When the
temperature of the medium falls by the value of the switching differential, the control
thermostat reverts to contact connection 1-2.
When the internally adjusted switch-off temperature of the thermal reset limit thermostat
(RAZ-TW..) is reached, contact connection 1-2 changes over to contact connection 1-4.
When the temperature of the medium falls by the value of the switching differential, the
thermal reset limit thermostat (RAZ-TW..) reverts to contact connection 1-2.
