Space HMI and Remote Room Sensor Installation
Space HMI faceplate(s) (refer to

), remote room sensors (refer to

and smart controls may be ordered and shipped separately. These components measure temperature and assist in
controlling the unit. These components should be installed in a safe location, free of influence from external heat sources.
Install sensors in areas indicative of the average room temperature, and away from heat-producing appliances. HMIs and
remote room sensors can be installed directly to industry-standard junction boxes, either surface mounted or recessed
mounted. HMIs have a built-in temperature/relative humidity (RH) sensor, which is typically used to help control the
automatic function of the unit.
The HMI can also be configured to control the unit from a remote location manually. They can be configured not to use the
internal temperature/relative humidity sensor. In this configuration, the sensor in the HMI is ignored in automatic
operation. Multiple HMIs can be connected to one unit for temperature and R/H averaging. All combination
temperature/humidity HMIs will use a vented standoff. Mount the static pressure tube close to the HMI to obtain proper
room conditions.
A max of 4 additional HMIs can be daisy-chained together. Place an End-of-Line (EOL) device in the last HMI connected.
