1 INTRODUCTION

RHT-Air comes with a high precision and stability sensor to measure both
temperature and relative humidity. Because it operates with a microprocessor, it can be fully configured through it s USB and IEEE 8 02.15.4 interfaces, using Modbus RTU commands. The software DigiConfig enables for all the eq uipment’s res ources to be configured.
RHT-Air can be configured to display the temperature and Relative Humidity measured or even, the temp erature and the Dew Point
RHT-Air should be connected (via wireless) to an AirGate-Modbus so that its registers can be read whenever it is in operation.

3 MECHANICAL INSTALATION

RHT-Air was designed to be attached to walls. By removing the equipment’s
cover, users will have access to two molding holes of the base, as shown in
Fig. 4. The equipment should be attached with the sensor capsule facing downwards in order to ensure precision and the specified level or protection.

4 CONFIGURATION

4.1 CONFIGURATION VIA USB INTERFACE

Initially, the first conf iguration must be done through USB interface.
Remove the four set screws of the front panel of the equipment RHT-Air, taking the necessary precaution not to apply force on the internal connector of the electronic circ ui t.
In order to configure it through a USB interface, connect the cable as shown below. The external power cord should not be used during the configuration.

After removing the front panel, change the position of the jumper (J1) to “BAT” so that it can be supplied through the battery. Replace the front panel, by placing the four set screws, taking the necessary precaution not to apply force on the internal connector of the electronic circuit.

RHT-Air is manufactured with the jumper (J1) set in the position “EXT” for external power supply .

5.1.1 RECOMENDATIONS FOR INSTALLATION

Conductors of small electric signals must be separated from activation conductors or higher current or power in the system’s plan, if possible in grounded electroducts.
The instrument’s supply must come from a network proper for instrumentation.
In control and monitoring applications, it is essential to consider what may happen when any part of t he system fails.
The use of RC FILTERS (47 and 100 nF, series) in parallel with contactor and solenoid coi ls, etc. is recommended.

5.2 BATTERY POWER SUPPLY

RHT-Air can be supplied by an internal battery whenever the equipment is
not energized by the electrical grid. Below are guidelines on how to proceed for supplyin g power with a battery:
Remove the four set screws of the front panel of the equipment RHT-Air, taking the necessary precaution not to apply force on the internal connector of the electronic circ ui t.

5.2.1 REPLACING THE INTERNAL BATTERY

It is possible to check the battery’s charge through register “29”. A full y charged battery typically has a power above 3.6 V. As you use the RHT-Air, the power of the battery will gradually decrease. It is recommended that you check the value of registry “29" regularly so that when it reaches below 3.3 V, the battery can be replaced.
Note: Even when the power is below 100 %, the equipment will operate normally.
Only suitable replacement battery for this product is:
Remove the four set screws of the front panel, taking the necessary precaution not to apply force on the internal connector of the electronic circuit. After removing the front panel, replace the battery, taking the necessary precaution not to to uch the electronic circuit.
MANUFACTURER: OMNICELL
MODEL: ER14250HD
Insert a new battery and replace the front panel carefully, placing the four molding screws.
