No. Havenwise acts as another layer of intelligent control that uses some clever tricks to keep you comfy while minimising bills. We are constantly tweaking the settings in the background to ensure best performance at all times. Changing settings on the physical controller or in the manufacturer’s app can risk causing conflicts between Havenwise logic, and the hardware.

Heat pumps are cheapest and most efficient in “open loop”: This is where as many radiators or underfloor heating circuits are left fully open. It may sound counter-intuitive, but zoning your home by limiting heat to unused rooms is almost always more expensive with a heat pump than heating everything slowly and evenly. For the energy enthusiasts among you, Heat Geek have an excellent article here.

All this means that to run a heat pump in the cheapest way, the bigger risk is actually overheating rather than underheating. Radiator TRVs or physical thermostats can be used sparingly as temperature limiters in rooms which frequently get too hot. We recommend in particular tuning your bedroom radiators to ensure it doesn’t get too warm when you sleep.

From the Havenwise app, sign in with the Havenwise account you created during onboarding. From the home screen, you can select the heating icon to set up your comfortable temperature requirements.When setting your temperature schedule, there is no need to consider your tariff, setbacks, or pre-heat times.

Just what temperature you need to be comfortable, and when. Havenwise does the rest to deliver these temperatures in the cheapest way possible. Where there is no heating setpoint for a period, it defaults to a 18°C temperature setpoint. For most people, we see a single setpoint during waking hours often being sufficient.

It is important not to use manufacturer controls for this. Havenwise’s smart control requires the Havenwise app to setup and use properly. The setpoints in the manufacturer can be safely ignored.

From the Havenwise app, sign in with the Havenwise account you created during onboarding. From the home screen, you can select the hot water icon to set up your schedule.

When setting your hot water schedule there is no need to consider tariff, just the times a considerable quantity of hot water may be required (for example, showers or baths).

Our smart control will automatically shift the hot water cycles around to the cheapest periods, while still providing hot water at the times specified.

Heat pumps are great at maintaining a warm home, but they struggle to heat a cold home. Our recommendation is to heat your whole home to a fairly consistent and comfortable temperature. This can be counter-intuitive for boiler owners, as they would tend to keep certain rooms cold when not in use.

We recommend opening up your “cold” rooms to more store heat throughout the home, and you may find your heat pump doesn’t need to work as hard.

The Havenwise app can be used just like a regular thermostat. If you find you’re regularly too cold, the heating temperature setpoint can be increased accordingly.

Small increments make a big difference! If you’re usually warm enough but find you’re slightly cold as a one-off, there is a “boost heating" button in the Havenwise app. However, this is an expensive operating mode for heat pumps!

The Havenwise app can be used just like a regular thermostat. If you find you’re regularly too warm, the heating temperature setpoint can be decreased accordingly. Small increments make a big difference!

If you’re too warm in only one or two rooms, consider limiting the temperature in those rooms with radiators TRVs. Or for the technical, you can balance those radiators down: This reduces the heat output of the radiator and makes for a more consistent room temperature.

Yes, but first consider that a Legionella cycle may already be handled by the heat pump’s physical controller. This should be disabled.

A Legionella cycle can be scheduled by going to the hot water scheduling screen in the Havenwise app, and selecting a single day to target a hot water temperature of 55°C.

Finally, there have been discussions on just how necessary a Legionella cycle is. One thing homeowners on Agile should consider is that whenever energy prices are negative, we will automatically heat your hot water to 55°C+.

Usually a poor connection is due to a weak WiFi signal to the internet gateway connected to your heat pump. The gateway should have been appropriately positioned during installation. If it remains an issue, WiFi range extenders can be used to give a helping hand.

Rarely, our connection to the heat pump manufacturer can be interrupted if either their systems or ours encounter an issue. In these circumstances, Havenwise control will resume automatically when connection is restored.

Havenwise control will be automatically re-established when the internet is restored. The heat pump will continue to operate with the last settings we communicated to it until this happens.

If this turns out to be an extended period, the physical heat pump controller can be used as normal.
