RELATIVE HUMIDITY CONTROLLER
The RHC-1 Relative Humidity Controller is our most recent development in total humidity control. It is switchable between humidify and dehumidify. The
RHC-1 has a built- in onboard sensor which is accurate within +/- 3% with a set differential of 5%. Perfect for plant zone environments, reptile habitats,
or just about any application requiring accurate response and control.
Plug your humidity equipment into the 120 volt 3 prong piggy-back cord.
The RHC controller is universal and will work with 120v, 220v, or 240v - 50 or 60 hz automatically.
EXPLANATION OF OPERATION
Here is an explanation of how this controller is programmed to perform. It has a dead ban (differential or hysteresis as you prefer) of 5%. This is
the amount of humidity it will correct between coming On and going Off.
Dehumidifying mode: if your setpoint is 50% the controller will come On at 55% and bring the humidity back down to your desired 50% setpoint. So that is
a 5% allowance above your optimum setting.
Humidifying mode: if your setpoint is 50% the controller will come on at 45% and raise your humidity to your setpoint of 50%.
• Humidity Range: 5-95% RH

The controller is to be connected by a standard 115 VAC NEMA 5-15 plug and socket. Units may have an optional plug in sensor or an integral sensor.
The controller is enclosed in a corrosion proof anodized aluminum enclosure. The enclosure is capable of being wall mounted. The controller has
power and on indicators. The control has a switch to select humidify and dehumidify functions.
TYPE OF CONTROL: The control may be switched between Open on Humidity Rise (Humidify) to Open on Humidity Fall (Dehumidify). The output is energized
until the sensed humidity reaches the setpoint.
SETPOINT: The adjustable setpoint is the off point for either mode. The setpoint is adjustable by a knob over a 0-100% RH range. The differential between
the on and off points is fixed at 5% RH.
INDICATORS: Power on is indicated by a red indicator. The output power is indicated by a green indicator.
STORAGE TEMPERATURE: -40 to 120 F.
OPERATING TEMPERATURE: 40 to 110 F.
HUMIDITY: 5 to 95% RH, non condensing.
ENCLOSURE SEALING: NEMA 1 enclosure, not sealed to moisture. Control, and sensor, must be protected from chemical or water sprays.
INPUT CONNECTION: Standard three wire NEMA 5-15P cordset.
INPUT POWER: 120 VAC, 15 A., 50/60 Hz.
OUTPUT CONNECTION: Integral NEMA 5-15R socket.
OUTPUT POWER: 120 VAC, 15 A., 1/2 Hp
EXTERNAL SENSOR: External sensor wiring is low voltage isolated signals.
Connections by standard RJ-12 crossover
