    Wireless room thermostat query

    Fortunately, non of the wiring goes through the closed/sealed section of my boiler. At least no wiring that I need access too. I’ve checked and it’s all accessible and runs under the boiler unit into and out of the front panel. The biggest pain would be removing the existing cable run to the old...

    Wireless room thermostat query

    Thanks guys, yep definitely H/R cable/flex. Will check bandq and all the other usual haunts.

    Wireless room thermostat query

    Cheers telectrix. The two L terminals I’m referring too are in the BDR91 room stat/programmer. One of these will link to the L from the boiler, But which one? Note: I’m piggy backing N/L from the boiler.

    Wireless room thermostat query

    Hi guys. Just bought a Honeywell CM700 series wireless room stat/programmer with BDR91 relay box/receiver to link with Worcester Bosch 28CDi combi boiler. Using a 4-core will take L/N feed from boiler to L/N in receiver and route the Ls/T1-A and Lr/T2-B. But there are 2 L terminals in the...

    Wiring to replace old room thermostat to new digital

    Existing programmer integrated with boiler is a manual dial clock type, where you depress buttons to select the duration for which you require heating. Nothing digital, after all it’s a 20 yr old Worcester Bosch 28cdi. 1568830903 Thanks Pete. Yes to T&E, by the looks of it, E being connected...

    Actually skip that, just realised it wired directly to the combo boiler. This fast snowballing. Would a wireless be any simpler? 1568829293 Actually skip that, just realised it wired directly to the combo boiler. This fast snowballing. Would a wireless be any simpler? Source URL: Wiring to...

    Wiring to replace old room thermostat to new digital

    I’m replacing a tatty old mechanical Drayton room thermostat with a sleek digital Flomasta 7635G. Could a wise wizard please help decipher the code known as the wiring diagram in the pictures attached. Theoretically, given the ‘standard’ wallplate, I should just remove the old and pop on the...
