Product Identification
Product Overview
The HT relay series has dual outputs to measure temperature and humidity of the air inside a room. They are
designed for use in hospital rooms, laboratories, and other spaces that require precise environmental control.
Two separate relays control the setpoints for heating and cooling when in thermostat mode or humidifying and
de-humidifying when in humidistat mode. The slide switch position determines the output type (amp or volt). To
maintain accuracy, keep vents clear of dust, debris, etc. The HT is warranted for period of ve years.

* The HS sensing element has a 1-year warranty. The element is not a part of the 5-year product warranty.
** Accuracy is specified with 24 VDC supplied power with rising humidity.
†Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.
‡If the 0° to 50°C (32° to 122°F) scaling range is selected, the device’s operating temperature range still applies.
One side of the transformer secondary is connected to the signal common, so an isolation transformer or
dedicated power supply may be required.
RTD/Thermistors in wall packages are not compensated for internal heating of the product.
EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper
surge protection (EN 61000-6-1:2007 specification requirements).

Installation
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Locate the tab at the top of the sensor housing. Using only the minimum required force, press this tab down and pull the cover
outward from the top. Set the cover aside.
Housing, Top View
Tab
2. Remove the backplate by unfastening the sensor from the bottom of the backplate and pivoting the sensor outward.
3. Punch out wire opening in the backplate.
4. Position the backplate vertically on the wall, 4 ½ feet (1.4 m) above the oor. Locate away from windows, vents, and other
sources of draft. If possible, do not mount on an external wall, as this might cause inaccurate temperature readings.
5. Mount the backplate onto the wall using the screws provided.
Five screwholes available; use a minimum
of two for secure mounting.

1. Temperature calibration allows for a calibration oset of ±9.9° (C or F), at the user’s discretion.
2. Relative humidity allows for a calibration oset of ±9.9% RH, at the user’s discretion.
RH and temperature can be eld calibrated by moving the RUN/CAL jumper to the CAL position.
