Humidistat

An adjustable humidistat activates the exhaust fan when the humidity becomes too high. The CO₂ is turned off when the dehumidification mode is activated.

Fan Timer

The exhaust fan is activated on a scheduled basis in order to insure fresh air delivery to the room. Control knobs allow adjustment of the fan timers interval (frequency of operation) and duration (amount of run time). The timer is optimised for use the CO₂ injection: the CO₂ is turned off 10 minutes prior to the next scheduled fan run time.

CO₂ Timer

Timer working in concert with the fan timer releases CO₂ once every timer cycle. A unique feature of the 100 allows an upgrade to complete CO₂ control, simply by plugging in the Telaire CO₂ monitor

CO₂ Setpoint Control

The 100 also includes a CO₂ sensor interface and setpoint control that maintains precise CO₂ concentrations. The CO₂ is turned off at night or when the exhaust fan is running.

Light Sensor (Photocell)

Senses "day" to activate the CO₂ controller. Can be used with natural, artificial and combination lighting schemes.
