Local thermostats and
humidistats are assumed to schedule "unoccupied" status with appropriate relaxed temperature and humidity setpoints.
One solution is to place the
humidistat in a location that's both easily accessible and provides an accurate reading of the patient's immediate environment.
The other systems also have a
humidistat to control dehumidifiers or change system operation in response to the space-relative humidity level.
Senses when water in vaporizer gets too hot because
humidistat is stuck on.
During the cooling season, even if the indoor air relative humidity is not mechanically controlled (there is not a
humidistat that senses the indoor conditions and activates the system response), the air, which is a mixture of outdoor air and recirculated indoor air, is partly dehumidified while passing through the cooling coil of the fan coil.
Disconnect the wiring to the solenoid valve and
humidistat and remove the old humidifier (Photo 1).
Its digital controls include an automatic
humidistat and a built-in hygrometer.
Does your MC system only control temperature (no
humidistat built into the system)?
Consider installing a heat recovery unit with a
humidistat.
Better models have adjustable fan speeds, a built-in
humidistat and automatic shutoff.
This control method can be implemented by using a
humidistat wherein a humidity sensor measures the RH in the controlled space and heating of the air is initiated by the controller when the RH goes above a pre-set value.
Automatic controls for water-level height and a solid-state
humidistat ([+ or -] 2%) are factory installed.
