control (contact closes on rise in space RH above control
setpoint) or a combination thermostat--humidistat control
device such as Carrier’s Edge
R

isolated contact set for dehumidification control. The
humidistat is normally used in applications where a
temperature control is already provided (units with
PermierLinkt control).
