MLM Wall CO2 Thermostat

The Rickard MLM/MLC Wall Thermostat with CO2 control has been designed to give the user primary temperature control and secondary CO2 level control to maintain comfort levels and keep CO2 levels in check respectively.

The CO2 thermostat senses temperature and controls the temperature of the zone by modulating the damper of each VAV diffuser. When the CO2 value rises above a threshold value, the diffusers open fully until the CO2 value is brought down to an acceptable level. Thereafter the diffuser returns to primary temperature control mode.
