M thermal Mono
4.2 M thermal Leaving Water Temperature (LWT) Selection
The recommended design LTW ranges for different types of heat emitter are:
 For floor heating: 30 to 35⁰C
 For fan coil units: 30 to 45⁰C
 For low temperature radiators: 40 to 50⁰C
4.3 Optimizing System Design
To get the most comfort with the lowest energy consumption with M thermal, it is important to take account of the
following considerations:
 Choose heat emitters that allow the heat pump system to operate at as low a hot water temperature as possible
whilst still providing sufficient heating.

Make sure the correct weather dependency curve is selected to match the installation environment (building
structure, climate) as well as ender user's demands.
 Connecting room thermostats (field supplied) to the hydronic system helps prevent excessive space heating by
stopping the outdoor unit and circulator pump when the room temperature is above the thermostat set point.
