How Do Electronic Humidistats Control Switches Work? 

A humidistat is an instrument that measures the Humidity of the air. Humidity is the measure of moisture. It is expressed in % (percentage). Moisture is the physical quantity, and humidity is its measure. 

In a 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 humidistat will function as a "cycle" the conditioner ON or OFF automatically in response to internal humidity level instead of responding to internal temperature levels.

For example, say an electronic humidistat is set up at 70% humidity level, see how it operates: 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 humidistats, R851V step controllers with integrated vernier, and Programmable & Non-Programmable Thermostats for Commercial HVAC operational and troubleshooting manuals.

R851V STEP CONTROLLER WITH INTEGRATED VERNIER STAGE

The Viconics cost-effective, designed R851V series step controller is a precise modulation of a multi-stage control application. A common application for a controller is a multi-step electric duct heater.

An integrated vernier control output will give a precise and full modulation of the load from 0 to 100% of the total capacity

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, making the process very simple for the 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.
