e. Battery Replacement.
The Batteries should be replaced every season, you will notice they need changing as gradually the
Push Buttons cease to operate the Control.
f. Changing the Receiver Batteries.
To change the Receiver Batteries remove the Ash Pan Cover and locate the electronic
receiver box, underneath the fire on the left hand side. Slide open the plastic cover to gain access to the battery compartment.
You can detach the Receiver by pulling it off its Velcro Pad to make access easier but remember to put it back in the same
position. Replace with 4 x AA good quality alkaline batteries, operate the Push Buttons to check the Batteries are fitted correctly.
Note: Only Change The Batteries When The Fire Is Cold
2.4 - LIGHTING & CONTROLLING THE FIRE - THERMATRONIC RF CONTROL
The Thermatronic Control System is a battery operated gas fire control system that uses a microprocessor to provide the working
sequences needed by the fire, and when used with an oxypilot has all the safety features required by law and CE approval.
Commands are accepted by the microprocessor when buttons are pressed. An audible beep means that the command is received,
and the push button should immediately be released.
Using the System
Control can only be achieved if the Handset is pointed at the Fire.
The red light will flash each time you press the Handset.
a. Ignition.
Simultaneously press and hold the red button and the right upper button (linked by line) until a
short acoustic signal confirms that the sequence has begun, then release the buttons.
Continuous audible signals confirm that ignition is in progress.
When pilot ignition is confirmed the motor will open the valve to maximum flame height – this takes about
30 seconds.
b. Flame Height Adjustment.
Press the small flame button until the flame height is at the desired position.
If you try to go beyond the preset low flame minimum height the main burner will turn off leaving the pilot
burner alight (this is the standby position).
You will learn from experience the preset low flame minimum height.
You will learn from experience the minimum preset flame height.
c.
Relighting the Fire.
To relight the fire from the standby position, or to increase the flame height from low
flame press and hold the large flame button until the desired flame height is achieved. Please note that
you can have the flame height anywhere between maximum and preset low.
For fine adjustment simply tap the small or large flame buttons.
d. Switching Off.
Press the red/off button on the Handset.
2.5 - GENERAL
a.
Battery replacement is recommended at the beginning of each heating season, or when an acoustic error
message sounds during ignition.
b.
Error Message – Long signals (0.8 second tone – 0.2 second break) during ignition – probable cause - batteries
in electronic receiver box are nearly discharged.
c.
Error Message – 5 second continuous tone – probable cause – cable disconnected or on/off switch on valve is in off position.
d.
Batteries - Electronic Receiver Box - 4 x AA good quality alkaline - Handset - 1 x PP3 good quality alkaline.
e.
To change the Handset battery slide open the plastic panel on the back of the Handset.
f.
To change the Receiver Batteries remove the Ash Pan Cover and locate the electronic receiver box, underneath the fire on the left
hand side. Slide open the plastic cover to gain access to the battery compartment. You can detach the Receiver by pulling it off its
Velcro Pad to make access easier but remember to put it back in the same position.
Note: Only Change The Batteries When The Fire Is Cold
2.6 - RESETTING THE MERTIK MAXITROL LOGIC CIRCUITS - IF THE HANDSET DOES NOT WORK
ONLY APPLIES TO THE THERMATRONIC HAND HELD RADIO FREQUENCY CONTROL
Basic Reset -
It sometimes happens that (such as when the handset buttons are pressed out of sequence) the fire stops
working because the logic circuits get confused and need to be reset.
To do this, simply remove the 4 x AA batteries from the Receiver Box (see section 2.4f above), wait for 1 minute and then refit the
batteries. Wait for another minute and then point the handset at the fire and press the red/off button. Wait for another minute and then
start the fire as normal. If the fire does not start repeat the resetting procedure. If the fire still does not work a Full Reset can be tried.
Full Reset
- If you obtain a new handset the control system will need to learn the handset’s unique code via a Full Reset. Also, if the
fire is not working and the Basic Reset has not worked a Full Reset can be carried out:
Remove the Ash Pan Cover and locate the electronic Receiver Box.
Locate the Reset Hole on the side of the Receiver and using a pen press and hold in the Reset button until you hear two beeps.
The first beep is short and the second beep is long. After the second beep release the Reset Button.
Now on the Handset, within the next 20 seconds press and hold the Small Flame Button until you hear two additional short beeps
confirming the code is set in the Receiver.
If you hear one long beep the Code as not been set so repeat the procedure.
If after carrying out the above procedure the situation is not corrected it will be necessary to contact your Installer.
Note: For the Installation/Service Engineer
- Resetting of the Handset & Control System is also covered in Section 21.1 page 24.
