Ecodan with FTC7 controller DHW schedule

Cressie · 2025-01-24T22:12:00Z

Hi, recently had a Ecodan ASHP fitted with solar panels. Has anyone had much experience with the FTC7 controller when it comes to scheduling the DHW. It asks you to prohibit times which I assume prohibits the use of the heating to allow the DHW to work? I’m looking to set DHW to come on for a couple of hours in the early morning and again early afternoon for about 90mins to take advantage of the solar panels (DHW temp 47 degrees). Any advice to make sure I set the schedules properly?

@davidalgarve There are 2 heating modes for DHW Eco and Std, Eco as it suggests uses less input power but takes longer, so if you aren't on that already you could change it.

There is also the speed of the pump to the cylinder you could alter that and see what impact it has on input power, either way its going to take longer to heat the water if you are using less power.

Hi Gary,

I am away from home at the moment so cannot check, but is that feature only on the FTC7? I don’t recall the Eco feature on my FTC6. Pump speed 3 or 5 doesn’t make much difference.

The hot water mode is the settings on FTC6, I think you are thinking of separate pump speeds for heating and DHW which is only on FTC 7, its in the video below.

To change HW pump speed on an Ecodan with FTC6 then you need to move the manual switch on the side of the pump with 3 different positions

Thanks Gary. I had forgotten the Normal/ Eco setting and remembered it as soon as I saw the picture, and I will now try it and see what difference it makes.

On my Hydrobox, there is no facility to change pump speed manually, but I can change independently the pump speed for both house and DHW on the control panel.

Currently I have both on 3 and wonder if reducing this for DHW, would result in more cycling.
