RE: Testing new controls/monitoring for Midea Clone ASHP  

By benson, 2 weeks ago

  Via the modbus using the svenar (ESP home?) controller. It is odd how yours works, and this device doesn't. @tasos definitely in the serviceman settings unfortunately. Sounds like you might have a new...

  They are on my Midea unit. I wonder if your more recent unit is different? Can you remind of the end to end details of how you connect to your heat pump? My auto-adapt script doesn't turn the unit of...
Transparent RE: Buying large amp bidirectional RCD and RCBO  

By Transparent, 2 weeks ago

  There won't be many RCBOs with a 100mA trip rating because that's stipulated for fire protection, rather than human safety. However, Proteus do manufacture a 63A rated Type-A RCBO here in the UK. A...

RE: Electricity price predictions  

By JamesPa, 2 weeks ago

  @jeff I think you are making the mistake of thinking that there might be an easy way to reduce carbon emissions, ie either that technology is somehow going to bale us out or that politicians are mi...

By Lucia, 2 weeks ago

  @drei I’ve been working through hundreds of radiator options trying to finalise the design for my heat pump remedial work. My current “designer” radiators are underperforming by around 35% at a 50 °C ...
