WAR - Weather Adaptable Regulation
What can this function do for you?
The aim of this function is to dynamically change the water temperature used for heating, compensating for the outside weather. If it is very cold outside, you require more heat compared to when it is warmer outside to end up with a comfortable house. This function will thuss compensate the increasing heat loss the colder it get outside.
This will allow the heat pump to run at a lower, more efficient rate saving you energy. This will reduce cycling of the compressor to increase its lifetime.
How to setup?
Temperature profile
Here you can program three points, where you give the outside temperature and the corresponding target water temperatures.
The first (top) point is the highest outside temperature, by default this one is set to 15 °C. This corresponds to the maximum outside temperature the Panasonic accepts.
The last (bottom) point should be the lowest outside temperature you will realistically experience in you situation.
With the center point you can adjust the curve more to your liking. This will give you the ability to give you a bit more heat when freezing for example.
This will give you the WAR temperature profile graph.
Default values: xxx
Result
The actual outside temperature is used to find the corresponding water temperature according to your given settings. The result will be rounded to whole degrees celcius and shown at Calculated temp..
Advanced
If you want to use the WAR functionality of the Panasonic itself instead of this flow, you can export the Temperature profile to your HeishaMon / Panasonic.
Notes:
- The Panasonic has its own outside thermometer, this is typically located in the little black rubber tube on the back of the device. It’s quite inaccurate, especially if the sun is allowed to reach it, it is strongly recommended to use a proper outside sensor.
- Outside temperature range: -20°C - 15°C
- Water temperature range: 20°C - 60°C
- The Panasonic internally works with 2 points, instead of the 3 in this flow
- If you do not require three points, use 2 identical Water temperatures but unique Outside temperatures
RTC - Room Temperature Correction
What can this function do for you?
This function corrects the water temperature based on the actual room temperature. It is mainly desgined for small corrections to prevent an under- or overshoot in room temperature.
The basis for the setup is the difference between actual (Room actual) and target temperature (Room setpoint).
When it is too warm, the default water temperature for Heat is decreased by 1, 2 or 3 degrees celcius, and vice versa.
When properly configured this will result in a very stable indoor temperature, on the other hand, when inproper configured it can result in excessive cycling of the heat pump, causing extra wear and energy use. So please take your time to set it up right for your situation.
How to setup?
First enter a desired temperature at Room setpoint.
Secondly you need to enter at which point the water temperature will be changed by 1, 2 or 3 degrees celcius. This will take a bit of experimenting, for example if you use floor heating smaller deltas work better because by its nature it is slow to respond. When using radiators you can increase the deltas. A decent starting point is a change of 1 degree at a delta of 0.3, 2 degrees at 0.6 and 3 degrees at delta 1. Try to make small changes at a time and observe the result for at least 1 or 2 days.
Default values: xxx
Automatically disable heat
Additional to the upper section, you have the option to turn off heating completely when the temperature is way too high. Of course, when the temperature lowers again, you can set the trigger at which point the heating should switch on again.
This function will remove Heat from the Operating Mode. For example: if your Panasonic is operating in mode 4 Heat + DHW, it will be changed to mode 3 DHW only. When using mode 0 Heat only, then the heat pump will turn off.
Default values: xxx
Notes:
- The Panasonic has its own inside thermometer located in the Remote Controller, it’s quite inaccurate, and really not suitable for this kind of finely controlled corrections. Please use a custom indoor sensor with an accuracy of 0,1°C , for example a BMP280 or BME280. Be sure to place it somewhere out of direct sunlight and draft
- The chart shows 1 datapoint every 60 seconds
SoftStart
What can this function do for you?
This function tries to reduce the frequency of the compressor asap after starting. This will likely give you a longer run, uses less energy and generating less noise. It does make heating slower.
Default behaviour of the heatpump means the compressor will go to medium to high frequency (Hz) until the returning water temperature (See Temp. inlet (PV) at the Home screen) approaches the Final water temperature. Only then the compressor ramps down.
With the SoftStart function enabled, the Panasonic will be fooled to believe it is almost at the desired water temperature. This should cause the compressor to ramp down within minutes. When ramp down has occured, the water temperature will slowly be increased to the intented value. This all happens internally and is not visible for the user, but you can see the corrections in the log.
Minimum runtime
This will set the period this function is active. Is does not necessarily mean the compressor won’t turn off within this time limit. Normal internal logic of the Panasonic still applies, so when the water is warm enough the compressor stops. This is where the following option steps in.
Default value: xxx
Max water temp. increase
This will set the maximum increase in water temperature on top of the normally calculated water temperature. The higher incease allowed, the longer the compressor will run, but of course, the higher the overshoot in room temperature could be.
Default value: xxx
Notes:
- This functionality is effective after a defrost cycle when it is cold
- This function works only for Operating modes which include Heat

Ik heb de eerste drie functies herschreven, please shoot.

Ik verzin maar wat hier, wat zijn default waardes die overal wel enigszins goed zouden werken denken jullie? Dus ongeacht welk type verwarming/huis etc.
The first (top) point is the highest outside temperature, by default this one is set to 15 °C.
Is dit zo, of is het slim om dat in te stellen?
SoftStart:
- This functionality is effective after a defrost cycle when it is cold
Is dit nog relevant, het werkt toch gewoon altijd goed inmiddels?
