HUMIDITY SENSORS INSTALLATION AND COMMISSIONING GUIDE
01. SAFETY PRECAUTIONS
· Read all instructions in this guide before operating the air conditioning unit. Failure to do so may result in damage to the unit and void your warranty.
· Turn-Off power from mains supply by removing fuse or switching the circuit breaker to the Off position before installation or servicing this control interface.
· Follow sound LOCK-OUT/TAG OUT (LOTO) procedures to ensure that power supply is not re-energised accidentally.
· The sensors described in this guide has a power supply of 24 VAC. · Installation and servicing must be carried out only by a qualified technician. · Ensure that the unit installation complies with relevant council regulations and building code standards. All
electrical wiring must be in accordance with current electrical authority regulations and all wiring connections to be as per electrical diagram provided. · WH&S rules and regulations must be observed and will take precedence during installation process. · Only use these sensors with an ActronAir air conditioner as described in this installation guide.
02. GENERAL FEATURES
The CRH-D and CRH-S humidity sensors are utilised in ActronAir Hercules,Tri-Capacity, VCC and Genesis air conditioning systems when the optional Reheat or Economy (Enthalpy) cycle is needed. The CRH-D model is designed for duct mounting to measure and monitor relative humidity in the supply air through the ductwork during the Re-heat cycle; it is installed on the return side when operating in Economy Cycle. Conversely, the CRH-S model is mounted on the wall and measures the indoor humidity relative to the outside air. Both sensors are equipped with 8 DIP switches for mode selection and setting the sensor’s address as described below:
DIP 1-5 Address On (128-159)
ON
DIP 6-7 Off-Off = Supervisory CM100
ON
ECE
12 3 4 5 6 78
12 3 4 5 6 78
Off-On = Modbus 1,8 N,2 On-Off = Auto (Supv C – Modbus)
On-On = Modbus 1,8 E,2
DIP 8 Off = 19200 Bit/sec
On = 9600 Bit/sec
· Select address (DIP 1-5). The selection is made in 5 Bit binary code. Example: Off-Off-Off-Off-Off (128) / On-Off-Off-Off-Off (128 + 1 = 129). See table below.

1. Activate the sensor by following steps 2.1 and 2.2 from procedure when sensor is used as Room RH.
2. Set the “Room Humidity” parameters via G. Service menu and then “f. Service settings” (Gf Screen).
3. Go to “c. Thermoregulation” (Gfc Screen) sub-menu and then to “Thermoregulat. Gfc2”, to set the Return Humidity parameters.
NOTE: “Return Humidity” means “Room Humidity”.
