Installation Requirements

Items Supplied

Tools Required

Determine Primary Pump Type

The heat pump may be installed with a PWM pump (vari-able speed) or a standard pump (fixed speed).
To determine which type of pump has been installed, check for connections to the control board at B1 and B6.
If the primary pump is connected at B1 and B6, it is a PWM pump and no further action is required.
If there are no connections on B1 and B6 and the primary pump is connected at B7 and B8, it is a fixed-speed pump and the supplied relay must be installed with the heating pump as shown opposite.
The order in which you connect the wiring is not important.
The 2-core cable used to connect the relay to B6 and B7 on the Samsung control board is provided.
Add a wire link between B20 and B22.

STEP 1:

Configure the Samsung Controller

Change the following settings on the Samsung controller.

Turn off Water Law mode.
Navigate to the ‘Service Mode’ by pressing the up and down arrows together. Enter the password.
Go to ‘Water Law’ and find ‘2091 External Thermostat Application #1’. Set to ‘Not Use’.
Turn off any hot water schedules.
Select ‘DHW’ on the controller. Press the cog icon and navigate to ‘Schedule’. Ensure that no schedules are stored.

STEP 2:

Install the MIM-B19N Board

Install the MIM-B19N board into the Samsung outdoor unit.
Follow the manufacturer’s instructions included with the MIM-B19N.
WARNING Ensure that the installation work is performed in accordance with the installation instructions.
Incorrect installation of equipment may result in electric shock or fire.

STEP 3:

Complete Connections

Connect the Homely Hub to the MIM-B19N board with data cable.
The data cable may be extended using the supplied gel connectors. We recommend using Belden 8723 or stranded Cat-5 cable.
A single twisted pair must be used. Connect the A terminals with one wire and the B terminals with the other.
The supplied 120-ohm resistor must be placed between the A and B terminals as shown.

STEP 4:

Connect the Power Supply

Connect the power supply to the Hub v1 as shown and plug into a power outlet.
NOTE It may be necessary to install a new outlet on a spur if there is not one within range.

STEP 5:

System Configuration

Follow the in-app instructions to connect the Node to the Hub, connect the Hub to a WiFi network and complete the Homely configuration.
