Electromechanical TR and TW
• Temperature control or limitation with single-pole changeover microswitch
• Switching capacity contact connection 1-2: 0.2...16 A, AC 250 V
contact connection 1-3: 0.2...2.5 A, AC 250 V
• Mounting choices: surface-mounted on pipes or storage tanks
Use
Typical applications:
• In heat generation plant (control or supervision of the water temperature, control of
pumps, valves, etc.)
• For general use in heating, ventilation and air conditioning plant
Function
When the externally adjustable setpoint of the control thermostat (TR) is reached on
rising medium temperature, contact connection 1-2 changes over to 1-3.
When the internally adjustable switch-off temperature of the thermal reset limit thermo-
stat (TW) is reached on rising medium temperature, contact connection 1-2 changes
over to 1-3.
When the temperature of the medium falls by the value of the switching differential, the
contact connection reverts (1-2 closes, 1-3 opens).
