Installation Guide
E3X-T02-U2W 24VAC Thermostat
Overview
e 24VAC ermostat provides digital temperature control of heating and cooling–with
wireless communication to multiple ILLUMRA devices. It is designed for use on PTHP/
PTAC Systems, 4-pipe or 2-pipe fan coil systems, and most basic gas/electric furnace/air
conditioning units. Solid-state control outputs allow switching of electronic and relay
loads of 1.5 amps. is control operates from a single setpoint with automatic changeover
between heating and cooling. e fan cycles on/off with calls for heating or cooling or can
operate continuously in either low, medium, or high speed. e control can be placed in
economy mode or off mode with 40° freeze protection. Economy mode is enabled and
disabled by one or more compatible transmitters.

Programming the Thermostat
CAUTION: ILLUMRA Relay Receivers are to be installed and/or used in compliance
with relevant electrical codes and regulations. If you are unsure about any portion of
these instructions, please contact a qualified electrician. ese devices are intended for
indoor use, for permanently installed fixtures, and for dry locations.
Connect the thermostat to a 24VAC power source for initial setup. DO NOT

Programming the Radio Receiver
e thermostat can be configured to operate with many ILLUMRA transmitters. Depending on the transmitter type and the intended
application, the thermostat will need to be programmed to operate in Rocker Mode, Momentary Mode, Toggle Mode, or Scene Mode.
Multiple modes can be used with one thermostat. For transmitter installation instructions, see appropriate installation guide. Select the
desired Learn Mode below to program the thermostat.
CLEAR MODE:
Clearing the Switch Memory
In order the clear the switch memory within the thermostat, use the following steps:
Step 1: Press and hold the UP and DOWN butttons until CLR appears on the display (approximately 10 seconds). is will delete
all associated transmitters from the memory.
LEARN MODE 0:
Rocker Mode - Wireless Switch Control of Thermostat
Rocker Mode is usually used with ILLUMRA Wireless Light Switches. e thermostat goes into occupied mode when the top of the
rocker switch is pressed and unoccupied mode when the bottom of the rocker switch is pressed.
Step 1: Place the thermostat into Learn Mode by pressing and holding the UP and DOWN butttons until LRN appears on the
display. e display will alternate between LRN and 0 indicating that it is in Learn Mode 0 - Rocker Mode.
Step 2: Press one of the rockers on the ILLUMRA Wireless Light Switch. e display on the thermostat will briefly display ADD
indicating that it has added that transmitter.
Step 3: e display will resume alternating between LRN and 0 - add more transmitters as desired for this mode (up to 30).
Step 4: To delete a transmitter from the thermostat, press the wireless light switch again. e display on the thermostat will briefly
display DEL indicating that it has deleted that transmitter.
Step 5: Exit Learn Mode by pressing and holding the UP and DOWN buttons until LOC appears on the display or the display
returns to normal operating mode. is indicates that all learned transmitters have been locked into memory on the
thermostat.
NOTE: ese steps are also used for Manual On/Auto Off - Occupancy Sensor Control.
LEARN MODE 1:
Momentary Mode - Keycard Switch Control of Thermostat
Momentary Mode is used with ILLUMRA Wireless Key Card Switches. e thermostat will be in occupied mode when the key card is
inserted and unoccupied when the key card is removed.
Step 1: Place the thermostat into Learn Mode by pressing and holding the UP and DOWN butttons until LRN appears on the
display. e display will alternate between LRN and 0 indicating that it is in Learn Mode 0.
Step 2: Press and release the UP button. e display will alternate between LRN and 1, indicating that it is in Learn Mode 1
- Momentary Mode.
Step 3: Insert a key card into an ILLUMRA Key Card Access Switch. e display on the thermostat will briefly display ADD
indicating that it has added that transmitter.
Step 4: e display will resume alternating between LRN and 1 - add more transmitters as desired for this mode.
Step 5: To delete a transmitter from the thermostat, remove the key card (if inserted) of a learned switch and insert it again. e
display on the thermostat will briefly display DEL indicating that it has deleted that transmitter from memory.
Step 6: Exit Learn Mode by pressing and holding the UP and DOWN buttons until LOC appears on the display or the display
returns to normal operating mode. is indicates that all learned transmitters have been locked into memory on the
thermostat.
NOTE: ese steps are also used for Auto On/Auto Off - Occupancy Sensor Control.
LEARN MODE 2:
Toggle Mode
Toggle Mode is available for future product releases.
Step 1: Place the thermostat into Learn Mode by pressing and holding the UP and DOWN butttons until LRN appears on the
display. e display will alternate between LRN and 0 indicating that it is in Learn Mode 0.
Step 2: Press and release the UP button. e display will alternate between LRN and 1, indicating that it is in Learn Mode 1
- Momentary Mode.
Step 3: Press and release the UP button. e display will alternate between LRN and 2, indicating that it is in Learn Mode 2
- Toggle Mode.
Step 4: Press the transmit button on the desired transmitter. e display on the thermostat will briefly display ADD indicating
that it has added that transmitter.
Step 5: e display will resume alternating between LRN and 2 - add more transmitters as desired for this mode.
Step 6: To delete a transmitter from the thermostat, press the learned transmit button again. e display on the thermostat will
briefly display DEL indicating that it has deleted that transmitter.
Step 7: Exit Learn Mode by pressing and holding the UP and DOWN buttons until LOC appears on the display or the display
returns to normal operating mode. is indicates that all learned transmitters have been locked into memory on the
thermostat.
