If the pointer starts to rise quickly, (enters the yellow or red zone within 30 seconds) switch off at the external isolator and remove all air from the system. 19. When satisfied that all air has been expelled, start this process again from step 12. 20. Remove demand for CH and DHW. 21. Compressor and fan will stop. 22. Circulating pump will continue to run for a period of time (default setting in BTC.). 23. Set the ATC and BTC - details in sections 11.2 and 11.3 respectively. IMPORTANT When putting the heat pump into use for the first time, watch the refrigerant pressure gauge on the side of the heat pump. The needle will rise over time when the temperature of the refrigerant increases. However, if this happens very quickly (e.g. rises into the yellow or red zone within 1 minute) then an air lock is present. Switch off power to the heat pump immediately, and purge any remaining air from the system. IMPORTANT Grant Aerona heat pumps should be stored and transported in an upright position. If not, the heat pump MUST be positioned in an upright position for at least 4 hours before being operated. 11 Commissioning 30 Commissioning 11.2 Setting the ATC Controller The main purpose of the ATC controller is to give an overall maximum temperature control over the heat pump. In contrast, the BTC controller will give accurate control over both CH and DHW temperatures, even if they each have different target temperatures. There are 3 main conditions the ATC can be set in: 1. OFF – no signal to the heat pump, irrespective of other heating controls. THE HEAT PUMP WILL NOT OPERATE IN THIS CONDITION. 2. Automatic (Sun Symbol) – The heat pump is in a fully automatic condition. Conditions such as running, defrosting, frost protection are all operative. 3. Stand-by (Triangle Symbol) - Only basic functions are possible. Frost protection and back up heater will not operate. Press the ‘M’ button to switch between ‘Automatic’ and ‘Standby’ settings. The ATC also has a series of fault codes which will help in any fault diagnosis, should an internal fault occur. Refer to Section 13.3 for details. Set the time function on the ATC using the following procedure. 1. Press the ‘SET’ button twice. The hour segments will flash. Using the buttons to alter the hour setting. 2. Press the ‘SET’ button again to set the minutes Using the buttons. 3. Press the ‘SET’ button to confirm your entry. 4. The clock is now set. Setting the ATC parameters: The table shown on page 31 gives a list of the parameters applicable to the ATC. Please note that there are parameters that MUST NOT be altered. Changing these parameters will adversely affect the efficiency of the heat pump and will invalidate all warranties. To alter a parameter, first press until you have reached the appropriate function. To alter the setting, press the ‘SET’ button once, then use the buttons to alter the value. Once set, press the ‘SET’ button to exit back to the function menu. If no button...
