CELECT DRF3 Wireless Programmable Thermostat

DRF3 RF Thermostat

1. The system includes one wireless thermostat controller plus one RF receiver.
2. Transmits up to 20 meter indoor.
3. Communicates at 868MHz (Europe Standard) and designed for unlicensed operation under FCC Part 15.

Warning:

1. If there is a dead zone in the RF communication. That means the receiver may not be able to receive the message from the transmitter. Before the installation, check the communication first. If the communication fails, relocate the receiver and transmitter location.
2. If the receiver has interference, set another transmitter address. Reset the transmitter and follow the setup instructions to reset the receiver.
3. It is recommended locate at least 30com distance from any metal objects (including the metal box) and at least 2 meter from any electronic devices e.g. radio TV, PC, etc. The metal objects or electronic devices maybe interfere with the RF communication, so maximum distance will be shorter.
4. Do not mount onto metal wall boxes.

Installation, Mounting

Caution: Turn off DRF3 and the electrical devices (e.g. heater, cooler) which will be connected before installation. It is highly recommended that the installation procedure is processed by trained personnel.

Installation Location:

The thermostat (Receiver and Transmitter) should be mounted on an inner wall 1.5m 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/cool generating sources.

Wiring:

Caution: Turn off the electrical devices and receiver before wiring.
There is 4-wire cable provided

Color	Connection
Brown	240Vac Live
Blue	240Vac Neutral
Black	240Vac Live
Grey	Device’s power input

It is recommended that a 10A fuse is fitted at grey wire.
(Please refer to the wiring diagram on the last page.)

Mounting:

Using the accessory screws and wall anchors provided, mount DRF3 with the key-hole at the back. The transmitter and receiver should be mounted on the wall and install the covers on them.

Install or replace the battery for transmitter:

Caution: Turn off the electrical devices and disconnect the supply to the appliances before replacing the batteries. Replace only with the same or equivalent type of batteries. Do not dispose the used batteries with
household waste. Refer to your local area for the proper disposal.

1. Pull out the battery drawer
2. Place the new batteries according to the marking on the battery drawer.
3. Dispose the old batteries properly. Slide the battery drawer back to its position.
4. Check if the thermostat works properly or not. Press “Reset” if necessary.

Start/Reset:

1. After wiring and mounting, switch off all the connected devices. Place 2 new AAA 1.5V alkaline batteries according to the polarities marked. LCD display will be switched on.
2. Press ‘RST’ to reset. The DRF3 will be ready to control the heater / cooler.
3. Switch ON the heater/cooler and receiver. The heater/cooler will remain OFF until transmitter activates the output ON withdisplayed on LCD.

Normal Time Mode:

1. Temperature detection starts and LCD displays the room temperature.
2. If Battery is LOW, will be On. The old batteries must be replaced with new one immediately.
3. Defrost function is activated with displayed when temperature is 5°C or below. Output will be forced to ON @ Heat & OFF @ Cool.
4. Below 0°C, transmitter will display LO.
5. Above 40°C, transmitter will display HI.

Temperature Setting Up:

1. Select the comfortable temperature by pressing or to desirable temperature.
2. Return the room temperature display after 10seconds with the icon disappears.

Jumper Selection

Delay / No Delay jumper:

Heater  Cooler
No delay     10sec    4mins
Delay           4mins   4mins
Choose the Delay option if compressor heat is connected.

Heater/Cooler jumper:
Select the heater option when a heater is connected to the receiver. Select the cooler option when a cooler is connected to the receiver.

Address setting:
In transmitter and receiver, there are dip switches to select the addresses. The receiver ignores the message which is sent by the transmitter with a different address.
