I have a Mertik Maxitrol remote control for my gas fireplace logs. It says that the remote control is made in Germany. I came with the gas logs that I purchased from a company call Sure Heat Manufacturing.

Questions:

1. Anybody heard of this remote control before?
2. Is it IR or is it RF?
3. If IR, I couldn't get my HTM MX-500 to recognize it's commands which are:
UP Flame and Down Flame (like volume up and volume down).

Any help would be appreciated.
Thanks,
Larry Williams

If it works from another room or you can put your hand in front of it and it continues to work, it's RF.

Also, IR remotes will have either an IR emitter sticking out the front (looks like a LED) or a shiney plastic shield over the emitter.

Yes, the remote is a IR type remote. I tried setting my MX-500 to AUX-155 and tried to learn the MX-500 the fire-up and fire-down commands from the Maxitrol, but the MX-500 did not "see" any of the Maxitrol commands.
Is the Maxitrol likely working on a protocol that is not learnable by the MX-500?

Just out of curiosity, how do you know the remote is IR? The fact that your MX500 can't learn the signals is certainly an indication that the remote is RF (but it's by no means conclusive).

Also, you don't need to set a learning remote to a specific setup code in order to learn.

Well, I tried blocking the "eye" of the remote with my hand, and pressed the up-flame and down-flame and observed that the red light on the receiver no longer blinked. I also tried the same thing by covering the "window" on the receiver and pressed the buttons on the remote and observed no action taking place. So, I am 99% sure that it is a IR remote. I am wondering if the fact that the remote was made in Germany have anything to do with the MX-500 not being able to learn the Mertik Maxitrol commands.
You said that you don't have to enter a device code on the MX-500 to learn the command, and I understand what you are saying. However, just to make sure, I had set the device code to AUX 155, which I thought made sense.

Can you think of any reason why the MX-500 cannot learn the code, or, is there any other trick that could be used to learn these codes to the MX-500. I tried holding down the up-flame key, also tapping the up-flame key, changing the angle that the two remotes as I tried to teach the MX-500, but no matter what I did, the MX-500 never seemed "to see" the commands of the Mertik remote.

Larry,

I have a gas log fireplace with a Maxitrol control valve with a standing pilot. The control valve operates with the remote by applying +/- 6vdc to a servo attached to the valve control. My remote is a SKYTECH that operates the Maxitrol Valve. It may be just like yours. My Skytech is an RF Remote that operates on 303.80 Mhz. No iR here. I too have a new MX 500 and would like to find a good way to use the MX500 with the fireplace.

I'll keep checking this thread and post If I find a way to make it work. I would need a dry contact control that would be momentary contact as long as the remote was sending. That would allow positive 6 volts to bring the fire up and negative 6 volts to bring the fire down. Can be an iR or X10 device.

Any ideas anyone?

this may help you

I have the same Mertik Maxitrol remote, with model # G30 on the back.

As far as I can tell, it's not an IR or RF based remote - it's ultrasound.

The previous link (from jimfrey504) has been changed, fyi:
[Link: mertikmaxitrol.com]

That document shows the frequency at which the remote control operates the ON and OFF.

Hello can anyone please help, We have gas logs, the numbers are MERTIX MAXITROL made in Germany, PMAX = 1/2 psi, GV34-B1A0A56, date 0348, 60/3,5 with 068657 listed on the plate below, the proble we are having is the gas logs are leaving soot piles on the fake logs and now there is soot build up and its coming out of the fireplace, its an double side open fire place with vent chimney, I can not verify if this set could possibly be for natural gas only and NOT propane gas tank such as we are on, this is used home purchase and we did not purchase the log set new, can anyone tell us how to verify what type of logs we have? thanks [email protected] Brian

Hi, did you download the pdf? It requires an authorised account number now & I wondered if you still have the details. Thankyou

I just happened upon this post while searching for Mertik Maxitrol Remote control G30 - ZRHS. Do you still have your gas log set with remote? Do you know who the manufacturer is & if I can still order another remote?

Mertik Maxitrol Remote systems are all ultrasound frequency and are all set the the same frequency.

Standard remotes (black) are a different frequency to the thermostatic remotes (silver with a digital lcd dispay)

i sell fireplaces and can confirm this as a fact.

the best place to get replacements is fef uk ltd, gazco fires, or glen dimplex UK ltd, FEF UK ltd being the cheapest of these options

To TEXASJETMAN, the logs are either laid incorrectly, there is insufficient ventilation in the room 100CM2 if the gas input is over 7kw or the fire is overdue a service... ensure the gas jets are not blocked and that you are using the correct log set for the appliance, mertik maxitrol is just a brand name for gas controls and is not the fire brand

You probably know more about this then I do by now; but I have a remote that is a G30-2RHT

I know it's been a while since this thread has been active and my input is not quite relevant because the remote control discussed in this thread is an RF one (I think)
But I have just had a great deal of trouble getting the IR commands from the Mertik G6R-H (IR) remote to work with the Pronto TSU9600 so I thought I would paste the hex codes here for anyone who has similar trouble in the future..

For the record, Prontoedit Pro didn't learn the commands correctly and I ended up using an RTI IR Learner Kit to do it and copied the hex codes from the RTI software over to PEP

I've tested these and they work perfectly.

ENJOY! :)
