S541.RF/RT3 (S541.RFT) Installation Guide
Overview
The S541.RF is a radio frequency (RF) transmitter
designed to function as a battery
powered switch monitor for use in
the INNCOM RF IRAS network. It
can also be used in conjunction
with virtually any “dry contact”
switch input to transmit closure
information to the e4 thermostat.
The RT3 (S541.RFT), a modified
S541.RF, comes equipped with a
temperature sensor and
dispenses with the wiring
harness for use as a low-cost remote battery
operated temperature measurement device only.
Installation
The installer must be a trained, experienced service
technician. When installing this product:
1. Read the instructions carefully. Failure to follow them
could damage the product or cause hazardous conditions.
2. Check the ratings given in the product guide to make
sure the product is suitable for the application.
S541.RF and RT3 (S541.RFT)
•Mount within operational range (70 ft. indoors) of any
devices it may communicate with
•Avoid possible sources of interference such as
metallic boxes, WiFi access points, water pipes
•Do not mount in areas of high humidity
RT3 (S541.RFT) (additional considerations)
•Mount in a vertical orientation with the ventilation
slits at the bottom edge of the unit
•Avoid direct sunlight
•Avoid direct air discharge (preferably closer to an air
intake point)
•Avoid areas around windows and exterior doors
Mounting
1. Remove the top cover
2. Mark the position of the screw holes and drill holes
3. Use the supplied double-sided tape to affix the unit
in position
4. Affix the unit with screws
5. Insert 2 AA batteries
6. Secure top cover

To function as part of the
S541.RF or RT3 (S541.RFT) must accept configur
and instruction from the e4 thermostat.
1. Set the room address used by the therm
parameters 10, 11, and 12.
2. Set the RF ZigBee Channel
using parameter 243. The default ZigBee Channel is
channel 26 and this value should be used unless a
different value is called for in the commissioning
documentation. The parameter 243 value will app
as “0F.h” for ZigBee channel 26. The following list
shows what displayed value parameter 243 should
have for the desired ZigBee Channel:
“00.h”=ZigBee Channel 11
“01.h”=ZigBee Channel 12
“02.h”=ZigBee Channel 13
“03.h”=ZigBee Channel 14
“04.h”=ZigBee Channel 15
“05.h”=ZigBee Channel 16
“06.h”=ZigBee Channel 17
“07.h”=ZigBee Channel 18
“08.h”=ZigBee Channel 19
“09.h”=ZigBee Channel 20
“0A.h”= ZigBee Channel 21
“0b.h”= ZigBee Channel 22
“0C.h”= ZigBee Channel 23
“0d.h”= ZigBee Channel 24
“0E.h”= ZigBee Channel 25
“0F.h”= ZigBee Channel 26
Prepare the e4 thermostat to
•If commissioning an S541.RF:
•On the e4 thermostat, access par
IOMAP Bind) and set the value to the IOMAP liste
in commissioning documentation, but DO NOT press
the DISPLAY button yet.
•If commissioning an S541
•On the e4 thermostat, access parameter 15 (T
Address Bind) and set the value to the Address listed
in commissioning documentation ,but DO NOT press
the DISPLAY button yet. This Address will typically
be “231”.
4. Remove th
the S1 switch once to put it in “ready to Bind” mode.
The LED will blink slowly to indicate that it is ready
to accept a “Bind” command. Immediately continue
with the next step because the S541.RF/RT3
(S541.RFT) will remain in “ready to Bind” m
only 30 seconds.
5. Press the Display
make it send the “Bind” command.
6. The LED on the S541.RF or RT3 (S54
rapid blinking, indicating that the “Bind” request sent
from the e4 has been acquired. Press the switch once
within 30 seconds to accept the “Bind” command.
The S541.RF/RT3 (S541.RFT) will RESET.
7. To confirm that the S541.RF or RT3 (S541.R
been correctly “Bound” to the e4 thermostat, press t
S1 switch 2 times. This will force the S541.RF/RT3
(S541.RFT) to transmit a message to make the e4
sound its buzzer 10 times. Hearing the e4 sound
buzzer 10 times indicates the S541.RF/RT3 (S541.RFT
and e4 are correctly bound and communicating.
If multiple S541.RFs or RT3s (S541.RFT) are
installed, each must have a unique Address. If c
for in the commissioning documentation, use
Parameter 15 “Address Teach” from the e4
thermostat and enter the Address value from
property specific commissioning list for each devi
by pressing Display.
For the first minute duri
in test mode (the RT3 (S541.RFT) has no test mode).
In that period, the LED will illuminate when the
device is actuated. For basic testing, use Paramete
19, Value 12 to check the entry door. To test balcony
or windows, check the e4’s LCD to see if BALCONY
or WINDOW is displayed when opened. For other
testing, refer to the commissioning documents and
to the S541.RF Engineering Manual.
