To avoid damaging the electronics, do NOT use metal tools to 
remove the batteries from the handset / receiver. 
▪ Without using a mains adapter, battery replacement is recom-
mended at the beginning of each heating season.
▪ Old or dead batteries should be removed immediately. If left 
in the unit the batteries can overheat, leak, and / or explode.
▪ Do NOT expose batteries (including during storage) to direct 
sunlight, excessive heat, re, moisture, or severe impact. Each 
of these conditions can cause the batteries to overheat, leak, 
and / or  explode. 
▪ Batteries must be kept within their recommended temperature 
limits (ambient battery temperature range:  32 °F  to 131 °F / 
0 °C to 55 °C).
▪ New and old batteries and different brands of batteries should 
not be used together. Mixing of various batteries can cause 
the batteries to overheat, leak, and / or explode.
▪ Low battery indication: frequent beeps for 3 seconds when mo-
tor turns.
▪ The V module for fan speed control and light / dimmer provides 
the receiver with power. The batteries in the receiver can be 
used for automatic backup in case of power outage.
NOTICE
To keep the receiver free from debris, dirt, and humidity, do not 
remove the receiver from the plastic bag until all construction 
is complete.
Radio Frequency Receiver and Handset
A code is selected automatically for all Mertik Maxitrol electronics 
from among 65,000 codes available. The receiver must be paired 
with a handset.
Synchronization Receiver / Symax Handset
(First time use only)
1.  Insert batteries or connect AC mains power. The module for 
circulating fan and light / dimmer includes a mains adapter. 
With mains adapter, batteries can be used for backup.
2.  Place  ON / OFF switch (if equipped) to ON position.
3. The receiver has to learn the Symax code:
   Press and hold the receiver’s reset button (see gure 28, page 
26) until you hear two (2) beeps. After the second, longer beep, 
release the reset button. Within the subsequent 20 seconds 
press the 
 button on the Symax. "CONN" and a running num-
ber from 1 to 8 are displayed on the Symax confirming the 
synchronization and data exchange is in  process (see gure 
13, page 7). Two (2) short beeps conrm the code is set. After 
successful synchronization the current state of the gas re is 
displayed on the Symax.
Figure 13: Synchronization of Symax handset in process
 NOTE: This is a one time setting only, and it is not required 
after changing the batteries in the Symax or receiver.
 NOTE: Both the receiver and the Symax transmit and receive 
signals  (bidirectional). The Symax and receiver sync 
status information every 10 s during the rst 2 min and 
afterward every 4 to 6 min.
 NOTE: When the RF receiver is placed in the appliance, the 
surrounding metal can reduce reception considerably.
NOTICE
The handsets and receivers are not interchangeable with previ-
ous electronics G6R and B6R-R8(9)U(T).
Synchronization Receiver / The  Puck Handset
(First time use only)
1.  Insert batteries or connect AC mains power. The module for 
circulating fan and light / dimmer includes a mains adapter. 
With mains adapter, batteries can be used for backup.
2.  Place  ON / OFF switch (if equipped) to ON position.
3. The receiver has to learn the Puck's code:
   Press and hold the receiver’s reset button (see gure 28, page 
26) until you hear two (2) beeps. After the second, longer beep, 
release the reset button. Within the subsequent 20 seconds 
press and hold the "–" button on the Puck (approx. 4 seconds) 
until two (2) short beeps conrm the code is set.
 NOTE: This is a one time setting only, and it is not required 
after changing the batteries in the Puck or receiver.
 NOTE: The receiver transmits and receives (bidirectional) sig-
nals and the Puck  (unidirectional) transmits signals. 
The Puck sends status information every 4 to 6 min to 
the receiver.
 NOTE: When the RF receiver is placed in the appliance, the 
surrounding metal can reduce reception considerably.
NOTICE
The handsets and receivers are not interchangeable with previ-
ous electronics G6R and B6R-R8(9)U(T).
