Principles of operating the

Greenstar Plus Hybrid Manager

Temperature

Sensor

FW200 Weather

Compensation Controller

Greenstar Plus

Hybrid Manager

Greenstar EMS gas-fired

or LPG condensing boiler

Greenstar Plus Hybrid heat pump

➊ Data is inputted into the FW200 controller

•

Calculation of system ﬂow set temperature

•

The appropriate strategy is chosen

– Strategy 1: Cost optimised

– Strategy 2: CO

optimised

– Strategy 3: Changeover temperature

– Strategy 4: CO

: cost mix.

•

Enter energy price ratio electricity/gas

➋ Greenstar Plus Hybrid Manager:

•

Calculation of ﬂow set temperature for the heat pump

•

Calculation of ﬂow set temperature for the boiler

Function:

Based on required system ﬂow set temperature, ambient

temperature, energy price ratio and/or primary energy

factors the overall highest possible system efﬁciency

is calculated.

➌ Boiler: (the higher temperature heating option)

•

Supports central heating up to the calculated ﬂow

set temperature for the system or supports all DHW

demand. Alternatively it can remain turned off.

➍ Heat pump: (the lower temperature heating option)

•

Supports central heating up to the calculated ﬂow

set temperature for the heat pump (boiler turns

on to reach peak demand) or supports 100% of

the central heating up to the required system ﬂow

set temperature (so the boiler remains turned off).

Alternatively the heat pump can remain turned off.
