Thanks for all the comments. -- Mark BR 'Volt free' = the thermostat contacts are provided 'dry' - that is an isolated pair of switched poles. The boiler end would have to apply some voltage in order to work out if they are open or closed. Could be as little as 3.3 or 5v, or 240 VAC |

In terms of current carrying capacity, it is probably adequate, however it is not well enough insulated to carry mains voltage. The exception to this may be if the combi has a 24V option for controls. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
