Thermostat (TST)
A simple volt free room thermostat can be used to operate the SHEVTEC PSU PANEL. The
output contact is required to close when a demand to open a vent is required.
When the demand is received, power is applied to the actuator outputs for 40 seconds in the open direction.
When the demand is removed, power is applied to the actuator outputs for 40 seconds in the close direction.
Both of these movements are subject to a 180 second lockout period which prevents frequent unwanted operation.
