EVERYTHING IS UNDER CONTROL
Dimplex LI MS and LI AS air source heat pumps utilise the WPM2004 Plus Heat Pump Manager designed to regulate, control and monitor the entire heating system.

AIR SOURCE HEAT PUMPS — BENEFITS OF THE UK CLIMATE
Compared with central Europe (where air source heat pumps are already very popular), the UK has a relatively moderate winter climate.
water pumps, mixer motor and supplementary heating sources are all automatically activated by the wall mounted WPM2004 Plus unit.
Water temperatures for up to 3 space heating circuits plus domestic hot water are individually programmable, providing maximum comfort and efficiency.
Simple to understand ‘warmer / cooler’ buttons adjust the temperature settings, while the heating system can be programmed to operate on a timed basis if required.
With average winter temperatures of around 5°C, seasonal co- efficients of performance comparable with ground source heat pumps are achievable, without the additional cost of expensive ground loop systems having to be installed.

1. WPM2004 Plus Heat Pump Manager
With air source heat pumps the Heat Pump Manager is supplied in its own housing for wall mounting.
2. Buffer tank
A 140L
A buffer tank extends operating times and ensures a minimum water flow rate through the heat pump in all operating conditions. Where the heat pump provides the sole source of heating, an electric immersion element can also be integrated to provide supplementary heating if required.
3. Heating system connections
A range of compact accessories are available to ensure a professional and
Compact manifold with
Hot water module for connection of an additional heating circuit (e.g. hot water heating).
Simultaneous connection of compact manifold and hot water module to the heat pump via a manifold bar.
4. Hot water cylinder
For the central hot water supply Dimplex offers a range of unvented
An integrated temperature sensor is connected to the heat pump manager, allowing the heat pump to automatically control the production of hot water as and when it is required.
