6 Specifications and Controls All Grant Aerona Heat Pumps ar e supplied with 2 controllers. 1 x heat pump controller (A TC) and 1 x temperature contr oller (BTC). The A TC is positioned inside the house/building and is normally used in an automatic condition.
Siting the Heat Pump 7 3 Siting the Heat Pump 1. Base The heat pump should be installed on a flat trowelled finished concr ete base 150mm thick. This base should extend at least 100mm beyond the unit on three sides. The edge of the concrete base on the side closest to the building should be flush with that face of the heat pump.
8 Siting the Heat Pump 3 Siting the Heat Pump The North face of a building will usually have colder ambient air than any other side. T o ensure maximum efficiency from the Grant Aer ona heat pump, position the unit on a warmer side.

However , it is possible to utilise a buffer if the end-user wishes to store hot water when ther e is no other demand placed on the system.

14 System Design Criteria Unlike a typical condensing oil or gas fired boiler that operates at a flow of 70˚C and a return of 50˚C, a heat pump operates with a flow of between 30˚C and 60˚C. The return temperature will depend on the load of the system at a given point in time.
Calculating Radiator Sizes 15 Most existing wet heating systems will use radiators as emitters. When the original system was installed, the radiators would have been sized according to the manufactur er’ s specifications.
16 Sealed Systems The following components are r equired to use the Grant Aerona heat pump as part of a sealed heating system. Due to the lack of space these components are not located within the heat pump, but have to be fitted external to the unit.
Electrical 17 8.1 General The Grant Aerona Heat Pump is very simple to install and to wir e. The units are designed to meet the need for simplicity – both in installation and in servicing. As a result, the wiring involved is both minimal and simple compared to other heat pumps available.
18 Electrical 8 Electrical Earth connections have been excluded for clarity . Ensure all earth connections are made prior to energising. Within the heat pump control panel, connect the wires as follow.
Electrical 19 8.4 Mains Supply Cable All Grant Aerona Heat Pumps contain a 3kW immersion element as a boost heat source. This element will energise under either one or two conditions : 1. When the external ambient air temperature dr ops between -5ºC and +5ºC.

Electrical 25 8.9 Extending the Electrics It may be part of the system design to incorporate Solar Thermal into the design. This is easily done with the use of an additional two-pole relay . Following the diagram in Figure 8-13 below will give the solar thermal system a priority over the heat pump when there is a demand for DHW only .
26 Domestic Hot W ater 9.1 T emperature Contr ol The desired hot water temperatur e stored in the cylinder can be adjusted on the BTC controller . As already mentioned, the heat pump works most efficiently at lower temperatur es but these temperatures ar e not suitable for domestic hot water which should always be stored at about 60ºC.
Domestic Hot W ater 27 NB. Setting this override switch to OFF does not stop the automatic operation of the immersion element. The requir ed relay , manual override switch and enclosure ar e available from Grant Engineering UK Ltd as a kit. For details of this Automatic Domestic Hot W ater Boost Kit (Grant Ref.

30 Commissioning 11 Commissioning 11.2 Setting the A TC Controller The main purpose of the A TC controller is to give an overall maximum temperature contr ol over the heat pump. In contrast, the BTC controller will give accurate control over both CH and DHW temperatures, even if they each have differ ent target temperatures.
