    RELATIVE HUMIDITY CONTROLLER (with remote sensor)

    Same as the RHC-1 except with the added feature of a 20 ft. remote sensor which is quite handy for those applications where sampling is necessary in a specific zone, or the area is inaccessible or for very small enclosures.

    The RHC-R Relative Humidity Controller is our most recent development in total humidity control. It is switchable between humidify and dehumidify. The RHC-R 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.


    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
    • Humidity Differential: 5% RH
    • Operating Temperature: 32-120ºF (0-50ºC)
    • Operating Humidity: Non-Condensing Environment (0-95% RH)
    • Voltage Input: 120 VAC
    • Voltage Output: 120 VAC
    • Max Amperage Rating: 15 AMPS
    • Frequency: 60 Hz
    • Dimensions: 4” Wide x 5-7/8” High x 2¼” Deep (10cm x 15cm x 6cm)
    • Power Cord: 6-ft, piggy-back 14 awg, SJTW rated
    • External Sensor Connection (if used): Std RJ-11 patchcord

    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.
    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
