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.
