Stock Humidity Controllers from O’Dell
We are often asked the proper way to control humidifiers. O’Dell has standardized on Vector Controls and their succinct line of humidity controllers. Here is an all-inclusive guide for choosing the correct Vector controls for your humidifier. All available online in our webstore.
NOR1-SDCH116A31 Duct Humidity Transmitter
This duct-mounted transmitter operates on 24 VAC/VDC and outputs either a 0-10 VDC or 0-20 mA signal, based on measured relative humidity. It is typically used with the TCI-W22-UH-W24 controller as a modulating high limit. It can also be used as a duct sensor for keypad setpoint applications. It requires three wires for installation and does not include display.
NOR1-TDCBHU On/Off Duct Humidity Controller
This duct-mounted controller operates on 24 VAC/VDC and can act as either an on/off humidistat for unit control or on/off high limit as a safety device. It requires four wires for installation.
NOR1-TCIW22UH Wall Humidity Controller
This wall controller operates on 24 VAC/VDC and has an integral humidity sensor. It can provide either an on/off or modulating 0-10 VDC signal for humidifier control. This model does not accept a modulating high-limit signal input and therefore a separate high-limit device is required. It requires three wires for installation.
NOR1-TCIW22UHW24 Wall Humidity Controller
This wall controller operates on 24 VAC/VDC and has an integral humidity sensor. It provides a modulating 0-10 VDC signal for humidifier control and accepts a 0-10 VDC input signal from high-limit sensor for dual modulation applications. It requires three wires for installation.
