TH-920D(TX) Programmable R/F Thermostat This Programmable R/F controlled Room Thermostat consists of a Transmitter Uni TH-920D(TX) and a Receiver unit RV-0356
(either volt-free or volt-output). Its installation requires no wiring and can be fitted in any normal operation environment within 30 meters range between transmitter and receiver. Unique facility of R/F-address code setting is built into R/F Receiver as part of commissioning procedure to ensure that your R/F Receiver will only respond to instruction sent to it from Transmitter. The special feature of blue-backlit & soft-Key which is made of translucent rubber allows Red LED shines through provides an easy operation in dim surrounding. There are 3 separate working frequencies, be sure to check descriptions on top right on out front of both Transmitter and Receiver, be certain marked frequency band areconsistent.
