The Dream ASHP only allows 1-2 degrees variation between heating temperatures. This is quite a large fluctuation of temperature for koi and therefore a StC 1000 allows +- 0.5 deg C . This video shows how to connect a STC to a dream unit. I take no responsibility for you damaging your thermostat or dream ASHP!
