jablotron UC-240 User Manual

UC-240 Twelve-channel receiver

The UC-240 is a 12-channel receiver of signals from TP-60TX
wireless thermostats or from JA-60 wireless detectors. The receiver
has 12 output relays which can be used to control various devices. LEDs
on the receiver’s front cover indicate the status of each output channel.

When used with wireless thermostats, the UC-240 can efficiently
control multi-zone heating and cooling systems.

JA-60M wireless detectors can be used to control the UC-240’s
output relays remotely from any switching device (switch, micro switch
sensor etc.). This can be convenient for automation or control tasks.

The UC-240 can also receive signals from JA-60S wireless smoke
sensors and JA-60G gas leak sensors.

Installation

1. Remove the 4 screws holding the front cover and open the housing.

Unplug the internal cable and remove the cover.

2. Attach the UC-240 in a desired place with two screws (provided).

3. Route cables through the housing and connect them to the

terminals (see terminal description and examples of wiring).

4. Plug in the front panel cable and reattach the front cover to the

housing.

Note: Do not locate any cable close to the receiver antenna and do
not install any other UC-240 closer than 2 meters (this could shorten the
working distance). If you need a receiver with additional channels, please
contact your supplier.

Off Channel is not used (no transmitter is enrolled)
Steady Green Channel has a transmitter enrolled, relay is off
Steady Red Relay is on (activated by the enrolled transmitter)
Flashing Green Communication with the enrolled transmitter is

down (Low battery in transmitter, radio interference
etc.)

Flashing Red Learning mode (to enroll a transmitter)

Enrollment of transmitters

For each channel of the receiver, a transmitter (thermostat or wireless
detector) can be enrolled the following way:

•

using button
(current channel will be indicated by its LED flashing)

•

install batteries to the transmitter (thermostat or detector). When
powered, the transmitter generates an enrollment signal and its code
is stored in the selected receiver channel’s memory

•

enrollment of the transmitter is confirmed by the constant lighting of

the green LED.
Only one transmitter can be enrolled to each UC-240 channel. The
transmitter can be enrolled to multiple receivers with out any restrictions.
If you try to enroll a new transmitter to an occupied channel, the new
transmitter will be stored and the former one will be erased.

Erasing of a transmitter

To erase an existing transmitter,:

•

using button

(current channel will be indicated by its LED flashing)

•

press the RESET button and the corresponding LED will turn off

Use and Maintenance

All enrolled transmitters (thermostats and detectors) transmit regular
checking signals. If the receiver does not receive the signal of an enrolled
transmitter for a certain period, it will indicate that communication with this
item is down (flashing green LED) and the corresponding relay will turn
off.
A reason for the lost connection can be low batteries in the transmitter.
Average life time of the transmitter's batteries is about 1 year. Each
transmitter checks its battery’s conditions and signals in advance if the
batteries are reaching a critically low state (see the transmitter manual for
details).
Another reason of possible connection failure can be from radio signal
interference in the working band of the receiver. In such a case the
UC-240 will usually indicate loss of communication with a multiple number
of transmitters. In this situation, check if there is any non approved radio
communicating device in the working range of the receiver.

Warning: manufacturer is not responsible for
any damage caused by improper installation
or non suitable use of this product.
