Heat Pumps & Solar Thermal – Legionella Control
Heat pumps often need to use the immersion heater to get the hot
water to a high temperature for the purpose of Legionella control.
This is an ideal application for the
External Boost input.
The immersion heater should ONLY be connected to the immerSUN, do
not connect the immersion heater to the heat pump or solar thermal
controller.
ON/OFF Control of Other Appliances
Only resistive loads (e.g. heaters) can be connected to the variable
power Heater 1 and Heater 2 outputs. However, it is possible to simply
switch ON/OFF other types of devices by using the
Threshold
option of
the
Multifunction Relay
.
Cylinder Destratification
The effective capacity of a hot water cylinder with a top mounting
immersion can be increased by pumping the hot water to the bottom of
the cylinder, therefore allowing the immersion heater to heat the top
section of the cylinder again. The
Multifunction Relay
has a
De-strat
Pump
control option for this purpose.
