RESIDENTIAL HUMIDISTAT

Modes of Operation

Heat-Only Mode

In Heat-Only Mode the humidistat will only turn on the humidifier when

the heat signal from the thermostat is on. This mode works well in winter

climates when humidity is only wanted during the heating season.

In Basic Mode the humidistat will turn on the humidifier when either a fan or

heat signal from the thermostat is on. This mode works well in any climates

that require humidity and in situations where humidity will be needed when

the heat is not running.

*It is recommended that Heat-Only Mode is activated during the summer

months in northern climates to prevent the humidifier from running during

the cooling season.

Eco Mode (Fan Wiring Required For This Mode, G, GF)

In Eco Mode the humidistat will turn on the humidifier when either a fan or

heat signal from the thermostat is on just like Basic Mode. Eco Mode also

adds the humidistat fan on signal. This will turn on if there has been 2 hours

of no heat or fan signals from the thermostat. The humidistat fan signal

will turn on the furnace fan for three minutes to check the humidity level. If

below the setpoint, the humidistat fan signal will stay on and humidify the

space for a maximum of 1 hour or until a heat or fan signal turns on from

the thermostat. A heat or fan signal from the thermostat will reset the 2 hour

timer. If the humidifier cannot meet the humidity needs via the humidifier fan

signal the humidistat will revert to Basic Mode to keep the fan from cycling

unnecessarily.

Performance Mode is for households that desire the most consistent

humidity levels. The humidistat will turn on the humidifier when either a fan or heat

signal from the thermostat is on. When the heat or fan signal from the

thermostat turns off, the humidistat will check humidity levels. If the humidity

level is below setpoint, the humidistat fan signal will turn on and humidify the

space for a maximum of 1 hour or until a heat or fan signal turns on from the

thermostat. Performance Mode also incorporates the 2 hour no activity timer

described in Eco Mode. If the humidifier cannot meet the humidity needs via

the humidifier fan signal the humidistat will revert to Eco Mode to keep the

fan from cycling unnecessarily.
