Weather Compensation
Your Cool Energy inverTech heat pump is equipped with intelligent weather compensation features.
This means your heat pump will adapt itself automatically based on the ambient temperature outside and the
system demand.
So for example if the temperature outside is warmer, it will lower the flow temperature to your heating system
and if its colder it will increase it automatically. This greatly improves the efficiency of your heating system and
we would recommend this is left turned on. Your installation engineer will discuss the best possible settings for
your property on installation.
Please see below the logic of the weather compensation and setpoints:
(As per setting - User configure U06 on page 23.)
Modes available to select:
1. Day mode : According to the ambient temperature and load requirements, the compressor runs at the maximum
frequency, and the fan runs at the maximum speed – Select for best system response times.
2.
Night mode : During the period from 20:00 to 8:00 of the real-time clock, the maximum speed of the fan shall not
exceed 500 rpm, and the maximum speed of the compressor shall not exceed 50Hz. These two parameters can be
adjustable, and other periods are in accordance with the day mode run.
– Select for quietest operation
4.
Low speed mode: As shown in the logic below, outside ambient temperatures / heat pump operation modes
correspond to compressor maximum speeds and temperature setpoints. – Select for best system efficiency
