Anti-condensation heater
A space heater can increase the internal temperature and keep dry inside actuator to avoid the freezing lubricant and moisture causing actuator failure under low temperature or high humidity. Heater is not recommended if the ambient temperature is higher than 35℃ (95℉). However, when the temperature varies much from day to night or between summer and winter, heater and thermostat are recommended.
Heater thermostat
The option can switch the heater off when the temperature inside the actuator is over 25±5℃ (77±9℉) .
Auxiliary limit switches
The standard model equips with the 1st & 2nd switches for fully-open and fully-closed. The option consists of the 3rd & 4th auxiliary switches which provide dry contacts for fully-open and fully-closed.
