TS820 Touchscreen RF Wireless Thermostat 110915 CAUTION:
1. Turn off TS820 electronic source and the electrical devices (e.g. heater, cooler) which will be connected before installation and maintenance. 2. The installer must be a trained service engineer. Installation Location 1. The thermostat should be mounted on an inner wall 60 above the floor in position where it is readily affected by changes of the general room temperature with freely circulating air. Prevent direct exposure to sunlight; dripping or splashing area. Do not place this unit at a location where air circulation is low, or where it has great temperature changes (e.g. near door). Do not place the thermostat near heat generating sources (radiators, hot air vents, TV or lights). 2. Wiring of receiver This thermostat works with receiver RT01R/MA. For thermostat use :
For heat-pump use : (need to connect W and Y) CAUTION :
TURN OFF any electrical devices before wiring. There are 5 terminals. Connect RH and RC to power supply. Connect terminals G, Y and W as shown in the figure above for Fan, Cooling and Heating. Push all cables back into wall prior to fixing to avoid trapping wires. Do not use metal conduit or of cable provided with a metal sheath. 3. Mounting System Setup mode There are 8 settings in the setup mode:
1. Calendar 2. 24/12 hours selection 3. C/F display selection 4. Fan HE/HG selection 5. Thermostat / Heat-pump selection 6. Span Selection 7. Delay/ Long delay selection 8. DST (Daylight savings time) selection 9. Screen lock selection Press and hold SYSTEM for 5 seconds to enter the setup mode. During setup mode, press CONFM to accept current setting and proceed to next setting. Press EXIT to discards changes and return to normal mode. Calendar 1. Base housing
- Adjust the base on the wall or junction box and ensure the base is at surface level and cover the junction box comfortably
- If necessary, pull the cables out at the middle hole of the base
- Place the 2pcs of wall anchors at the wall if necessary.
- Fasten the base with the 2pcs of long screws 2. Insert the 2XAA batteries into the thermostat battery case (Beware of wrong battery poles) 3. Hold the thermostat on the base. Align the screw blocks with the pins at the back of the thermostat. 4. Push the thermostat straight onto the base until snaps into place. Communication Setup 1. There is a blue 8-pin dip switch on both the transmitter and receiver. 2. Set them to be the same so that they can communicate to each other.
( 256 choices ) 3. After placing you thermostat, select FAN to ON instead of AUTO. 4. After the above step is made, wait for about 10 seconds. The receivers FAN LED should then be turned on. 5. In case the LED is not turned on, please try the following. i. Check both transmitter and receiver have the same address ii. setting. If problem continues, power down receiver for at least half a minute and then power it on. Then try toggle the fan status so as to check communication. Feature list:
