Could someone recommend best settings for a heat pump? Willing to pay for your help

[damspt]

hi, I’m new to this website, sorry if this is not the right place for this topic

I’m a new build home owner, been here for 2 months. First time using heat pump. I messed up with the settings and i have no clue what to do. What temps etc

looking for help to set the weather curve and whatever needs doing.

Hello.

Have you got a copy of the relevant Manual?

 

Page 20 of this manual appears to answer your question

WC curve is pretty straightforward, use you manual to find the correct things to change as far as settings

 

Curve start at 20 Deg outside set to minimum flow temp to 25 or minimum allowed flow temperature. At -6 outside for radiators set to 45 and UFH set to 35. That's a good enough start point.

 

Now wait for the heating season to start. 

 

In rooms with thermostats set to max and with radiators thermal valves set to max. Also set all timers to run 24/7.

 

Then let system run for 24 hrs, if overall house is too hot reduce the flow temp at -6 down, only adjust about half the overshoot, so if target is 21 Deg house and it up to 24, reduce flow by 1.5 degs. other way if too cold. Only adjust once each 24 hrs, until you get where you need to be.

Welcome.

 

I don't know how much you know about heating system, or the design/layout of your particular system, but as a general rule, low flow temperature heating systems are left 'on'. They add heat to the building when it is needed, not on a schedule i.e. 5AM to 8AM, 4PM to 10PM. Though it is possible to have times of lower building temperature i.e. when asleep.

The reason for this is that simple physics, energy (kJ or kWh) is power (kW) multiplied by time (s, seconds or h, hours). A building uses the same amount of energy to keep a constant temperature difference between outside temperature (OAT) and inside temperature (IAT), it just depends how it is delivered i.e. short, hot bursts, or longer, warm delivery.

ASHPs, specially with weather compensation (WC) automatically adjusts for outside temperatures, which helps with the system efficiency (CoP).

One spanner in the works is zoning. Zoning is really just the ability to isolate parts of the system, either automatically (radiator or room thermostats) or deliberately (physically isolating via a lock shield or similar).

If, after zoning, there is a limited amount of usable fluid in the system, the flow is impeded, or the temperature rises too fast, then the system can shut down with an error.

 

Usually with controllers, there is the ability to reset them to factory defaults. But there is also an 'installer' mode that usually needs a password.
