MLM WALL COMFORT & RELATIVE HUMIDITY CONTROLLER
The Rickard MLM/MLC Wall Comfort & Relative Humidity Controller has been designed to give the user primary temperature control and secondary RH level control to maintain comfort levels and keep RH levels in check respectively.
The Comfort & Relative Humidity Controller senses temperature and controls the temperature of the zone by modulating the damper of each VAV diffuser. When the RH value rises above an adjustable threshold value (RH% Threshold High), the diffusers open fully until the RH value is brought down to an acceptable level (RH% Threshold Low). Thereafter the diffuser returns to primary temperature control mode. The Relative Humidity of the supply air should be lower than the RH% Threshold Low value to
allow for the relative humidity to be controlled adequately.
