Power up the unit. A counter displays the numbers 1 to 9 followed by display of the controller model (172) for 3 sec. and the software version for 3 sec. Then the top of water tank temperature is displayed and the unit engages operation. The METROAIR AQUA HPM is now ready for use. -
Page 20: Controls And Operations
7 Controls and Operations 7.1 Control panel Optima 172 The METROAIR AQUA HPM is delivered with an Optima 172 control with factory settings so that the heat pump is ready for operation without additional adjustments. The factory settings are default settings that should be adjusted in accordance to the operational needs and user requirements in order to achieve optimal performance and utilisation of the system. - Page 21 P2: Controlling the auxilary electrical heater The “electric heater”-key is pressed and held. Then the setting can be changed with the arrow keys. At outside temperatures below 0°C it may be beneficial to use the electrical heater as a supple- ment for heating the domestic water.

7 Controls and Operations 7.3.1 Display view (main menu) The display show the various temperatures by pressing the arrow keys. Press until the number of the sensor of the desired temperature appears. After approximately 3 seconds the temperature is displayed. The relevant temperature is displayed for about 30 seconds before the display goes back to normal view. - Page 23 E2: T9 temperature set point Here a temperature can be set which can be used in connection with menu item E19 and temperature sensor T9. This is a separate sensor, which is not part of standard delivery. See E19=2, 4 or 5 for further description. Options: 0-30°C Factory setting: 21°C E6: Anti-legionella - week day...
- Page 24 7 Controls and Operations E13: Floor heating temperature Here a temperature is set, which can be used in connection with menu item E19=2, i.e., the minimum temperature, at which the circulation pump for the floor heating starts. If the temperature T8 (water tank) is less than the value set at menu point E13, the circulation pump stops.
- Page 25 E18: Number of hours Setting of number of hours for continuous run at fan speed mode 3 before automatically switching back to mode 2. This option is used by the menu item E17=1. Options: 1-10 hours Factory setting: 3 hours E19: Extra function This function controls relay R9: Solar collector, additional heat sources, heat sink, or damper control.

- Page 27 This value specifies the maximum evaporator temperature (T6) allowed. This prevents overload- ing of the cooling system at high ambient temperatures. Options: 0-30 °C Factory setting: 25 °C E25: Fan speed mode 1 + 2 If extraction of air for a longer period of time is required, mode 2 (P1) can be chosen. The fan will now run, until it is change to a different mode.
- Page 28 7 Control and Operations The required time (minutes) where the T10 input must be higher than the E31 set point before the heat pump starts in PV mode. This parameter allows filtering of input power and avoidance of heat pump starts on short spikes of excess PV power.

A point flashes to show that the system is powered. 2: Water temperature T7 (water tank, top) is displayed. 3: The time is displayed. Options: 1-3 Factory setting: 2 E50: Internal clock hours Here the hours of the clock are set.
- Page 30 7 Control and Operations Options: 0-23 hours Factory setting: 6 hours E60: Temperature difference between T5 and T6 This is an operational safety feature which indicates that the heat pump is not running properly, potentially lacking refrigerant or indicating that the solonoid valve does not close properly. If the T6 temperature (evaporator) is higher than the T5 temperature (before evaporator) + the value set in menu point E-0 after one hour with the compressor in operation, the compressor will turn off.

Page 33: Controlling Domestic Hot Water Heat Pump With Optima 170
7.7.1 Water heating When tapping hot water, cold water is supplied to bottom of the water tank. A sensor measures the temperature in the water tank. When the temperature has dropped 5°C below the set temperature, the compressor starts and the fan ventilates air through the evaporator. When the water is heated to the set temperature, the compressor (and fan) stops again. - Page 34 7 Control and Operations 7.7.4 Extra heating capacity If a situation arises where the domestic hot water heat pump is not able to provide enough hot water, it is possible to activate an auxilary electrical heater. About twice as much water can now be heated in the same period of time.
- Page 35 The call for heating (low water temperatures) can be suppressed during the sunny hours (only allowing for operation on PV power) and released for normal mode operation during user defined evening and night times. This is done by the existing low tariff function. [fig 21] The figures below illustrates typical installation options.
