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).

HTSeries TM

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.
