1. RS W Wireless Remote Temperature sensor The Smart Temp RS W is a precision manufactured wireless remote temperature sensor with many advanced capabilities Please take time to read and understand these instructions as if properly installed the RS W will prove to be an accurate and reliable temperature sensor Please contact Smart Temp or an authorised distributor should you have questions about the RS W sensor not covered in this manual Setup The Smart Temp RS W remote sensor is made up of two parts the battery powered temperature sensor transmitter and the 24V powered temperature receiver module These matched pairs serve to communicate temperature information from the sensor to the receiver module via 433 MHZ RF signal The temperature data is then read by the thermostat Pairing The RS W sensor sender and receiver module must first be paired before they can be communicate and transmit temperature data This simply involves setting the DIP switches in both the receiver and transmitter to the same value code Sensor Receiver C e Pairing E Switches E Pairing Switches Ce 24VAC T2 T1 0 aeai The sensor and receiver are fitted with a red switch block with 5 white switches These switches are marked 1 to 5 Before inserting batteries or powering the receiver simply set the same combination of On and Off on both the transmitter and receiver switch blocks to pair the two devices This must done while power2. then communication between the sensor and receiver is confirmed The sensor is powered by 2 AAA Alkaline batteries The battery life is typically greater than 1 year Smart Temp are able to offer remote sensors that provide temperature adjustment RS WA suitable for use with the Smart Temp family of thermostats When using the sensor with the Smart Temp SMT 770 amp SMT 920 thermostats the status button on the bottom of the sensor also initiates the after hours run timer The RS W status LED s will light when the receiver confirms the after hours run signal has been received Receiver The receiver is powered by 24VAC and provides temperature data to the thermostats remote temperature sensor terminals Snart Teng 3 LEDS on the receiver provide visual indication of the receivers function The power LED indicate that the sensor is powered The data LED blinks when temperature data has been received The status LED illuminates when the sensor switch has been pressed If no valid temperature data has been received for 10 minutes or a low battery condition is measured the receiver will continually hold the temperature output to the thermostat to a fixed 21C When the sensor battery is low the status light on the receiver will continually flash Specifications Size 90 x 90 x 21mm Mounting 60mm spaced Material ABS PC blend UV amp fire resistant Sensor 10K NTC type II Operating temp 5 to 45c Storage temp 30 to 95
3. Simply connect the RS W to 24VAC power and the T1 T2 terminals to the thermostat or zoning systems remote or outside air sensor terminals as required Three examples of typical wiring is provided above LED Codes The Smart Temp RS W has indicator LEDS to provide feedback of the operation of the sensor please refer to the table below for these LEDS function Sensor Status Will illuminate after test AH button is pressed if successfully paired with a receiver Receiver Power Shows the sensor is powered Data Will flash when it receives data from the sensor Status IIluminates when sensor test A H button on sensor is pressed Will flash when sensor low battery condition is detected QSrart emp Smart Temp Australia P L U20 1488 Ferntree Gully Road Knoxfield Vic 3180 Phone 03 9763 0094 Fax 03 9763 0098 www thermostat com au www smarttemp com au

5. ed down as these switch settings are remembered on power up This method of pairing using hardware switches is a quick and normally error free way of pairing It also permits visual confirmation of the pairing making it simple to confirm which sensor and receiver set are paired Pairing ensures no cross talk if you have multiple sensors within a single building provided they all use different switch combinations codes You are permitted to have 1 sensor communicate with multiple receivers ifall are using the same combination This permits you to send outside air data from 1 sensor to multiple thermostats within a building if desired Smart emp Sensor The wall sensor consists of a Saart Top temperature sensor a low powered radio transmitter 2 AAA batteries and asmallindicator LED This sensor will transmit temperature data to the paired receiver at least once every 5 minutes or with every 0 5c of measured temperature change what ever occurs first The communication between the sensor and receiver is bi directional After sending temperature data to the receiver the sensor waits for acknowledgement of the data being received If acknowledgement is NOT received the sensor will continue to re transmit the data At any time should you wish to confirm communication between the sensor and the receiver simply press the button on the bottom of the sensor for 3 seconds if the status LED on the sensor illuminates
