i have a vaillant ecotech combi boiler and i want to fit a wireless room thermostat the stat is a boss bps242rf and the wiring instructions are very poor all it says is: LX = Common L1 = Live feed to item to be controlled L2 = Changeover contact L = Live N = Neutral any ideas?
L&N on boiler to L&N controller Link L to LX on controller RT on boiler to L1 on controller It is a rebranded siemans RDJ10RF and is more trouble than it is worth. It will flash up low battery in a couple of months. The batteries are fine. Slide them out and back in and it will work for another week or 2. Then some times it will loose contact with the receiver and have to be reset which is more hastle. should work if your boiler has been set up for a stat Instructions for the boiler http://www.vaillant.co.uk/stepone2/data/downloads/b9/43/00/ecoTEC%20pro%20instn%20maint.pdf Page 28 I just do the controls baggy is your man to confearm If you are not sure what you are doing get some one in you could do a lot of damage
thanks matty, the boiler connections are different http://www.vaillant.co.uk/stepone2/data/downloads/d7/42/00/ecoTEC_installation_and_servicing.pdf pg 26 shows the connections that i have
I've got an eco tec plus and I have the vailant wireless controller vrt392f, not the cheapest, it's in a holiday home and I have vrdialog so I can monitor and control it remotely, the software communicates with the vrt392f as well as the boiler. I think this type of controller integrates more closely with the boiler so the boiler knows what the roomtemperature is so it can adapt the amount of heat needed to maintain the desired temperature which is a bit more advanced than the simple binary on/off controllers Its been very reliable so far.
