This document must be read in association with the i-KIR2 Installation Manual provided with the unit.
It is essential the manual is read and followed to ensure the installation is per manufacturer’s
criteria.
The purpose of this document is to assist with the commissioning of the heat pump parameters and
the connection of third party controls.

1. Pre-commissioning
1.1. Pre-Commissioning Checks
Prior to Filling with water
A) Ensure the heat pump is installed in accordance with the installation manual.
B) Ensure the power is isolated to the unit
C) Remove the side cover of the unit to expose the water pump, compressor and electrical
enclosure.
D) Check the pre-charge of the expansion vessel is set to 1 bar.

Fill the system with water
The system can now be filled with water to around 1 bar pressure.
Ensure that all air is removed from the system by mechanical
flushing. This heat pump has a pump run switch on the small PCB
under the front cover of the heat pump. This allows the circulation
pump to be run manually to help vent the system.
1.2. Heat Pump Controller
The heat pump controller must be installed and can be configured to be used as a room thermostat.
Accessing parameters –
1. For User level Press menu button for 3 seconds
2. For Install parameters hold down the 3 buttons
together for 3 seconds
3. The parameter number (4 digits) will be displayed, and the value of
the parameter. (2 of the 4 parameter digits will be flashing)
4. Change these (flashing) numbers using the up/down buttons, or
5. Change to the other 2 digits using the +/- buttons, or and
change these too if necessary
6. Press the Set button
7. The parameter value will now flash
8. Change value using the or buttons
9. Press the Set button to confirm the new value
10. To default back to the main menu, press together for 3
seconds. The controller will default back to the main menu screen.

2. System configuration
There are 2 common configurations, A or B for heating and either can also have DHW, C:
A) Heat pump using own controller as room thermostat
B) Heat pump using additional central heating controller as room thermostat
C) Heating configuration A or B with DHW
Set the parameters according to the 3 tables below.
2.1. System A: Heat Pumps controller used as room thermostat
So that the controller turns the heat pump on and off according
to the room set point on the controller set to 0
0 = Room Set Point
1 = Water Set Point
Flow temperature set point for heating
35 to 45 underfloor (depending on floor covering)
60 – radiators
Internal circulating pump configuration
0=always on (even when no heat demand, not recommended)
1=on/off based on buffer tank temp
2=on/off based on sniffing cycles
Time pump on when sniffing
Time pump off between sniffs
Start temp of frost protection on Room air temperature
