1 Instructions guidance

1.1 Product documentation

The instructions are an integral part of the system appliances and must be handed to the user on completion of the installation in order to comply with the current regulation.

• Carefully read the manual, to understand all the information to enable safe installation, use and servicing. No liability can be accepted in the event of damage for not complying with the guidance in this instruction manual.

These instructions consist of, Installation, Servicing, Fault Finding. The instructions are an integral part of the appliance and must be handed to the user on completion of the installation.

- Accessories installation instructions (motorized 2 port valve...)

2 System description

2.1 Concept of operation

The hybrid system consists of the following components:

-A Glow-worm Envirosorb 5 heat pump,

- A "Compact" hydraulic module,

- A boiler,

- The Systempro control unit

- A Climapro2 RF wireless programmable room thermostat,

- A wireless photovoltaic outdoor sensor

The following options may be added to the system:

- 2 port valves for zoning,

- A domestic hot water cylinder

The hybrid system’s concept of operation is as follows:

- The home's heat is generated by either the heat pump or the boiler, dependant on outdoor weather conditions, and the energy prices paid for gas and electricity.

- The software in the Systempro control unit constantly monitors outdoor temperature, and the co-efﬁ cient of Performance (COP). The control unit then decides when to switch between the heat pump or the boiler to maintain comfort levels, whilst maximising the efﬁ ciency of the system.

The switchover point must be determined in accordance with the respective energy costs (see the "Activation of control unit > Settings> Energy management" chapter).

4.1 Recommendations before installing

4.1.1 Heating circuit design

General

The heat transmitters may be low temperature (eg underﬂ oor heating or high temperature (radiator...).

The pipe sections are to be determined using a ﬂ ow / pressure curve (refer to the chapter Commissioning ► Heating circuit adjustment"). The distribution will be determined by the ﬂ ow corresponding to the power actually required, regardless of the maximum power that can be provided by the installation’s generators.

We recommend that you allow for sufﬁ cient ﬂ ow

to ensure that the temperature difference between the ﬂ ow and the return is equal to 7 K for ﬂ oor heating and 15 K for radiators.

"Activating the control unit" ►

Chapter 2 - System description). Connect the overheating safety device to the boiler power supply.

Water treatment

Existing system- It is essential that prior to installing the new appliances the system is thoroughly ﬂ ushed.

New system- For optimum performance after installation, the appliances and its associated central heating system should also be ﬂ ushed.

Flushing shall be carried out in accordance with BS 7593, a chemical cleanser can be used either Sentinel X300, X400 or Fernox F3 are suitable.

It is recommended to ﬂ ush existing systems ﬁ rst before ﬁ tting the new appliances.

• Ensure all cleanser is removed from the whole system before adding an inhibitor.

For long-term corrosion protection after ﬂ ushing, an inhibitor suitable for stainless steel heat exchangers can be used. Either Sentinel X100 or Fernox F1 inhibitor can be used.

The module is suitable for use on systems using softened water.

4.1.2 Heat pump circuit design

Make sure the heating circuit water ﬂ ow is greater

Installation pipework must be designed and installed to ensure venting of air from the system is possible.

The total volume of water for the heating circuit depends, among other factors, on the cold static load of the boiler’s expansion vessel.

- In GB, Guidance on vessel sizing is also given in the current

It is recommended that a drainage valve be installed at the lowest point of the installation.

- Drain taps shall be to the current issue of BS2879.

The maximum working pressure of the domestic hot water circuit is 10 bar. If the cold water supply pressure exceeds this, then a pressure-reducing valve must be ﬁ tted in the supply to the boiler.

In areas where the water is ‘hard’ (i.e. more than 200 mg/L of calcium carbonate), it is recommended that the hot water setting is reduced and that a scale reducer is ﬁ tted, refer to the manufacturer’s instructions or consult the local water company for additional advice.

12.8.5 Adjustment of HP circuit ﬂ ow

The heat pump is designed to operate with a minimum ﬂ ow of 750 l / h. If the ﬂ ow is less than 500 l / h, the heat pump will stop and the boiler will begin to function. Heating comfort will always be guaranteed, but energy saving will be compromised.

The heat pump is equipped with a ﬂ ow sensor and it is possible to read the water ﬂ ow directly via the control unit.

The HP circuit ﬂ ow should be between 750 and 850 l / h.
