Electronic Humidistat Control Switch Configuration

How Do Electronic Humidistats Control Switch Work? 

Humidistat is an equipment that measure the Humidity of the air. Humidity is the measure for moisture. It is expressed in % (percentage).Moisture is the physical quantity and humidity is its measure. 
In general sense we consider any automatic HVAC equipment functions as responsive to the internal temperature level. But when used in conjunction with an air-conditioning system, the electronic humdistat will function as  "cycle" the conditioner ON or OFF automatically in response to internal humidity level instead of responding to internal temperature levels.
For an example, say an electronic humidistad set up at 70% humidity level, see how operate it is: When the relative indoor humidity reaches 70 percent or above, the air conditioner will "cycle" ON, even if the thermostat setting does not call for cooling.

Here you will find three VICONICS series of electronic humidistat, R851V step controller with integrated vernier and Programmable & Non-Programmable Thermostats for Commercial HVAC operational and troubleshooting manual.

Winiring Schematic Diagram for VICONICS electronic Humidistat: H200 One or Two Stage

The H200 series is available with one or two outputs for maximum flexibility. Outputs can be of the following type: proportional, on/off, and pulse width modulation (PWM). In addition, a wide variety of mounting configurations is available. Sensing options include remote duct and room as well as integral room and duct

Programmable & Non-Programmable Thermostats For Commercial HVAC Applications
The VICONICS T7600 PI series thermostat family is specifically designed for single stage and multi-stage control of HVAC equipment like-rooftop and self-contained heating/cooling units.

User friendly product features an intuitive, menu-driven, backlit LCD display through the programming steps and making the process very simplefor user.

Accurate temperature control achievement is important to design the product because the product’s PI time proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based thermostats.
