TOWERSTAT RF Programmable Thermostat

TOWERSTAT-RF-Programmable-Thermostat-PRODUCT

INTRODUCTION

This thermostat can replace most common residential thermostats and is designed to be used with electric, gas or oil heating control systems or cooling systems.
Unlike conventional thermostat devices, this control is a new type of thermostat that separates the functions into two units. The Receiver serves for wiring connections and heat/cool on/off control The Transmitter serves as the user interface and for temperature sensing / control. the two units are linked by radio frequency (RF)
The advantage is that the user can keep the Transmitter nearby and can read/control the temperature of the living area in immediate use.

INSTALLATION OF RECEIVER

Caution:

  1.  It is recommended that this device is installed by a qualified electrician
  2. The appliance can only be mounted indoors and in areas free from any water or moisture
  3. A suitable fuse with a rating not exceeding 13A should be in the power line
  4. Wiring must conform to I.E.E. regulations

RF Address Code Setting
If there is another user nearby, e.g. in the next dwelling, your Receiver may be operated in error by their Transmitter. You may select a different RF address code to prevent this. The Receiver can only respond to a Transmitter with the same RF coding as its own address code. Please see the information below for an explanation of coding changes.

  1. To change the address code of the Receiver, simply push up one or more of the 5 ‘dip’ switch levers (see illustration below)TOWERSTAT-RF-Programmable-Thermostat-FIG.5
  2. To change the address code of the Transmitter, open the Transmitter housing (refer to the battery replacement section to open the housing).
  3. Remove one or more of the jumper links as shown in the illustration below.TOWERSTAT-RF-Programmable-Thermostat-FIG.6

Caution:

  1. The address code of the Transmitter must be the same as the address code of the Receiver. For any jumper link removed at the Transmitter, the corresponding dip switch lever(s) must be put to the ‘up’ position.
  2. Disconnect AC power and remove batteries prior to adjusting the address code.

Removing your old thermostat

Caution: to avoid electric shock, isolate the power of the heating/cooling system at the main consumer unit in your home. Read the following instructions carefully before disconnecting the wires.

  1. Turn off your old thermostat
  2. Remove the cover from the old thermostat
  3. Unscrew the old thermostat from the wall plate
  4. Now find the screws attaching the wall plate to the wall, and remove them. You should now be able to pull the wall plate a small distance from the wall. Do not disconnect any wires yet, simply locate the wires.
    Warning: After removing the wall plate, if you find that it is mounted on a junction box (e.g. a box similar to one behind a light switch or electric outlet) it may connect to a mains voltage circuit and there is a danger of electric shock. Please consult a qualified electrician.

Mounting the Receiver onto the wall/junction box:
The Receiver fixing centers may align with the screw fixings of the existing back box. In this case:

  1.  Remove the front cover of the Receiver.
  2. Connect the wires (see wiring diagram)
  3. Securely fasten the Receiver using the machine screws provided.
  4. Replace the front cover and installation is complete.

Mounting the Receiver onto the optional wall box:

  1. Remove the front cover of the Receiver
  2. Mark the position of the hole for the wall box
  3. Drill two holes and insert the wall plugs until they are flush with the wall surface
  4. Pull the wires into the wall box and fasten the wall box onto the wall
  5. Connect the wires (see wiring diagram)
  6. Securely fasten the Receiver to the wall box with the two machine screws provided
  7. Replace the front cover and installation is complete.

Wiring for 230v or volt-free applications
The Receiver has a volt-free contact but comes from the factory with a pre-wired red link wire which puts volts onto the switch. Leave the link in place for mains switching, or remove the link for volt-free switching.TOWERSTAT-RF-Programmable-Thermostat-FIG.7

Setting of Transmitter

Heating / Cooling Selection
To adjust the Transmitter for heating or cooling function, also for code changes, and to insert/remove batteries, the Transmitter back housing must be removed:TOWERSTAT-RF-Programmable-Thermostat-FIG.8
Once the back housing is removed, inside the transmitter you can find a three-position dip switch. The three switches control the temperature span and set the output for the heating or cooling function. Set the dip switches according to your requirements
Temperature span selection
Span is the difference between the turn-on and turn-off temperatures. For example, in heating systems, if you set the temperature to 200C and span to 10C, the heater will operate when the room temperature drops to 19.50C and turns off when the temperature rises to 20.50C. Set the dip switches (positions 1 and 2) according to your selection of temperature span as in the following diagram.TOWERSTAT-RF-Programmable-Thermostat-FIG.9TOWERSTAT-RF-Programmable-Thermostat-FIG.10

Battery installation

Your thermostat uses two ‘AA’ size batteries to operate. To power up the unit, insert two ‘AA’ batteries into the battery compartment of the front housing. When power is applied for the first time, the display should show time and the day as well as the room temperature. Press the RESET button after insertion of batteries (use a fine instrument such as a straightened paper clip to gently push the RESET button.
After installation of the batteries, push back the rear housing to the control center and then the stand. The Transmitter is now ready to be programmed. TOWERSTAT-RF-Programmable-Thermostat-FIG.11
