Power up the unit. A counter displays the numbers 1 to 9 followed by display of the controller model (170) for 3 sec. and the software version for 3 sec. Then the top of water tank tempera- ture is displayed and the unit engages operation. The NIBE MT-WH 2029-F/1FS is now ready for use. -
Page 21: Controls And Operations
7 Controls and Operations 7.1 Control panel Optima 170 The NIBE MT-WH 2029-F/1FS domestic hot water heat pump is delivered with an Optima 170 control with factory settings so that the heat pump is ready for operation without additional adjustments. - Page 22 7 Control and Operations P2: Controlling the electrical immersion heater The “immersion heater”-key is pressed and held. Then the setting can be changed with the arrow keys. The heat pump is supplied with an electrical immersion heater for heating of the domestic water. At outside temperatures below 0°C it may be beneficial to use the immersion heater as a sup- plement for heating the domestic water.

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 24 7 Control and Operations E2: T9 temperature set point Here a temperature can be set which can be used in connection with menu item E19 and tem- perature sensor T9. This is a separate sensor, which is not part of standard delivery. See E19=2, 4 or 5 for further description.
- Page 25 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 tempera- ture T8 (water tank, bottom) is less than the value set at menu point E13, the circulation pump stops.

The unit is used exclusively for heating domestic water within the set temperature limit. Auxiliary function for supplying a small floor heating unit or for alter- native heat input is available in the NIBE MT-WH 2029-F/1FS S model. 7.7.2 Performance The domestic hot water heat pump can heat 367 litres of water from 10 °C to 52.5 °C within... -
Page 35: Extra Heating Capacity
7.7.7 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 the built-in electrical immersion heater. About twice as much water can now be heated in the same period of time. You can set the temperature to which the electrical immersion heater is to heat the water. - Page 36 7 Control and Operations 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 de- fined evening and night times. This is done by the existing low tariff function. The figures below illustrates typical installation options.
