ᐅ Issues with heat pump control

I assume you not only have the Proxon domestic hot water heat pump but also a combined unit in the form of an air-to-air heat pump, meaning a central ventilation system with heat recovery and an integrated heat pump. In every living room, there is one (or more) supply air ducts (with heating elements for extreme cases), and the „stink rooms“ have exhaust air. That would be quite similar to our system.

A wood stove produces significantly more heat in a room of a new building than needed. Therefore, the ventilation system has a stove mode. As I understand it, the ventilation simply runs at maximum level then, which helps distribute the heat better throughout the house and ultimately reduces the heating demand. You should use this mode when the stove is on. However, it is not mandatory, and nothing will be damaged if you don’t use it.

Best regards

I really appreciate the direct answer. Yes, that is exactly what we have, and we are uncertain about the settings.

I have read the user manual, but it is even more confusing.

So just to be sure:

MANUAL OPERATION is when the stove is off, and STOVE MODE is when the stove is on, right?

But it’s not compulsory to use it, as far as I understand.

THANK YOU VERY MUCH

This is a drinking water heat pump. It does not provide heating; it only produces hot water. This is not a (!!!) heating system. You have a separate device for that.

There are two large units, and only this name is displayed. The main unit, which is the heating system, shows no name or type.

You will have to ask the local chimney inspector. In my case, the "chimney function" within the controlled residential ventilation system was a condition for him to waive the requirement for a pressure monitor in the chimney. An air-to-air heat pump is basically no different. The "stove function" ensures that the ventilation does not create negative pressure that could cause exhaust gases to escape from the wood stove.

In my case, the "chimney function" in the mechanical ventilation system with heat recovery was a requirement for him to waive the need for a pressure monitor in the chimney. An air-to-air heat pump is basically the same. The "oven function" will ensure that the ventilation does not create negative pressure that could cause flue gases to escape from the wood stove.

We are going to turn it on anyway, just wanted to be sure.

For me, the "chimney function" in the controlled ventilation system was a prerequisite for omitting a pressure switch in the chimney. An air-to-air heat pump is basically the same.

However, this should actually happen automatically. The building inspectors here don’t accept systems that require manual switching. Otherwise, the switch would be unnecessary. You’re lucky that things are more flexible where you are.

No, I don’t switch that off; it is permanently active.
