For this example, to access and activate Distribution circuit 2, you first need to enter the access code as described in the Commissioning
Guide. Then navigate to "Mix valves" in Settings and press the text "Distribution circuit 2".
On page 1, set the values for minimum/maximum supply line temperature. On page 2, you can adjust the heat curve for Distribution
circuit 2. Notice that, depending on if the distribution circuit is set as a radiator or floor heating system, the "Factory reset" button will set
different values. After all the adjustments are made, go back to page 1 and press the switch at the top of the page to activate the func-
tion and also make it visible and accessible in the menu for the end user.

1. Activate if the heat pump should be active in a primary /secondary installa-
tion. In a single installation no activation needs to be made in this menu.
2. Activate primary heat pump.
3. Activate if the secondary heat pump is a legacy heat pump.
1. Press the following Icon to add new legacy heat pumps to the system.
1. Fill in heat pump ID for Legacy heat pump (Legacy no1=ID 1, Legacy no 2=
ID 2, etc.).
2. Type the Legacy heat pumps kW capacity.
3. Every EM1 module supports 2 legacy heat pumps. Therefor set Modbus to
108 for Legacy 1 and 2 (ID 1 and 2) and Modbus 109 for Legacy 3 and 4, etc.
4. Choose whether the Legacy heat pump should be active for heat or hot
water or both.
5. Internal ID for EM1 connection. The number indicates which internal ID the
legacy heat pump will have when it communicates with EM1 (The numbers
have to be either 1 OR 2 within the same Modbus address).
6. Confirmation is needed when changes have been made, and will also need
a restart to take effect.
1. A pop-up with a restart icon is shown in the display whenever a restart is
needed. This pop-up is merely information.
To activate restart, navigate to the menu “Operating mode”, set the heat pump to mode “Off” and press the restart symbol which will
appear.

1. When this symbol is shown in the top bar, changes have been made that
requires a restart.
2. Restart button (Requires that you´re logged in).

There might be several changes that will need a restart to function.
The pop-up information can appear in more than one occasion during
a configuration, so when the final configuration is done, only one re-
start is necessary.
