For your new Daikin Altherma high temperature heat pump

Your new Daikin Altherma heat pump

In this manual you will find information and guidelines that will allow you to run your Daikin Altherma heat pump system in the most energy efficient and cost effective way.

We hope you enjoy a warm and comfortable winter season!

System overview

The heart of your new central heating system is a highly efficient Daikin Altherma air source heat pump. The heat pump heats the water which flows around your central heating and separately heats the hot water when required in your hot water cylinder. The central heating is usually controlled from a Daikin controller or programmable room thermostat which switches the heat pump on and off at preset times, sending warm water through the central heating. Most radiators have thermostats

(TRV’s) fitted to control the individual room temperatures.

Your heating system in detail and getting the most from it

Outdoor unit

Outside is the heat pump. This extracts heat from the air, even below 0°C and uses this heat to heat the water passing through the central heating and hot water cylinder.

The outdoor unit pulls in air from the rear, extracts the heat in the air, and blows the cooled air out the front. This is done automatically, and there is no need to set or adjust it.

If the rear of the outdoor unit gets clogged up with leaves or debris, the efficiency of your heating system can be reduced, this should be checked regularly and cleaned with a soft brush.

Similarly, don’t block the front of the unit up by leaning anything against it.

Hydrobox

The hydrobox is located below the hot water cylinder. This distributes hot water around the central heating and to the cylinder. The Daikin

Altherma controller communicates with the hydrobox for efficient use.

Cylinder

Hot water is stored in the cylinder. To ensure low running costs the cylinder is normally set to heat to 50°C. Your system is set up to heat the water in the cylinder at the time when it is cheapest.

If you have Economy 7 this will be during off-peak periods. If not, it will be during the day when the air temperature is higher. The cylinder is being heated when the symbol is shown on the Daikin Altherma controller. Once a week the water in the cylinder is heated to 60°C to ensure the cylinder remains free from bacteria.

Hot water preparation in detail

Your system is set up to heat the water in the cylinder at the time when it is cheapest. If you have Economy 7 this will be during off-peak periods. If not, it will be during the day when the air temperature is higher.

Programmable room thermostat

You may have a room thermostat installed in your property. It would be located in the hall or within certain rooms. It controls when the house is heated, and to what temperature.

It is likely the thermostat has been set to heat the house to 21°C in the early morning, lunchtime and evening, with a cooler 18°C at other times from Monday to Friday.

At weekends, it is set to 21°C from early morning until late evening, with 18°C over night.

Underfloor heating (UFH) and/or fan coil units (FCU)

If UFH heating is installed you may see a manifold in your airing cupboard or similar with pipes going into the floor. This will heat your floors, which in turn heat your home. If FCU are installed you will see them on your walls. FCU operate in a similar way to radiators, but a fan in the unit pushes heat into the space around it.

Heat emitters: radiators

Most radiators are fitted with Thermostatic

Radiator Valves (TRV’s) as shown in the picture which ensures rooms will not become too warm.

Temperatures are represented by numbers or roman numerals I, II, III, IIII. The higher the number, the warmer the room temperature.

Each valve should be set according to the temperature you wish to achieve.

Useful functions on your

Daikin Altherma controller

Central heating operation

This option will operate if you have a room thermostat controller installed. Use the button on the Daikin controller to switch on/off central heating. When the and room temperature is displayed too.

Use the and buttons to increase or decrease your desired room temperature. The maximum room temperature setting is 32°C.

Reheat function

This mode will prevent your tank from cooling down lower than a specified temperature

(as set-up by your installer). This will ensure your tank is always at a minimum temperature so you are less likely to run out of hot water.

On your Daikin controller press the button for 5 seconds to enable reheat. The icon will be displayed on your screen. To turn off the reheat function, press the button.

The icon will disappear.

Maximising your energy savings

To increase the efficiency of the central heating system, your heat pump will automatically vary the temperature of the water going through your central heating. The colder the temperature gets outside, the warmer the circulating water through your central heating.

This feature (called weather compensation or economy mode) should be selected on the controller, and the automatic symbol will show in the controller display. If this symbol is not shown, press the button.

When in the automatic (weather compensation) mode, if you feel the house is too warm or not warm enough you can adjust the central heating water supply temperature up or down by pressing the buttons on the controller.

Your checklist for diagnosing possible faults

If the radiator is too cold check that the radiator TRV is set to a high enough level.

A room may become warm enough without the radiator being more than lukewarm.

Is the programmable thermostat set too low?

Check that the temperature on the programmable thermostat is set high enough to start the heat pump.

Is the mains power switched off?

Check that the heating switches are switched

ON, including the switch located next to the outdoor unit.

In the event you have checked the points

opposite, and the system still fails to operate normally, you can manually reset the system by turning off the power, waiting 60 seconds then turning it back on.

If the system still does not operate

as normal, check the display on the controller for a fault code (typically a number and a letter for example 7H) and contact your housing association, making reference to the displayed code.
