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.

2 System description

2.1 Concept of operation

The Standalone system consists of the following components:

-A Glow-worm Envirosorb 5 heat pump,

- A "Standalone" hydraulic module,

- 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.

2.1.1 Operating principle in heating

The system is designed to provide a heating need of 6kW max at the reference temperature.

The heat generator consists of a heat pump and a hydraulic module equipped with an electric heater. The heat emitters can also be low temperature (heated ﬂ oor, gentle heat radiators...) or medium temperature (steel panels...). In order to always obtain the best comfort/economy trade-oﬀ , the module heat pump and/ or electric heater supply the heating installation with hot water at the temperature necessary to obtain the desired ambient temperature.

When the power of the heat pump is no longer adequate to ensure heating, the self-controlled electric heater in the hydraulic module can operate simultaneously in steps of 2 kW up to a power of 6 kW (in the case of a heat pump ≤ 5 kW the top-up power is limited to 4 kW when the heat pump is operating). This guarantees optimal use of the heat pump while guaranteeing that the total electrical power consumption will never exceed 6kW. When the heat pump is not operating, the electric heater can reach a power level of 6kW independent of the outside temperature conditions.

ATTENTION: Risk of damage to the appliance or to its

b i

surroundings.

IMPORTANT: Important information.

1.4 Guarantee registration

We recommend you complete and return as soon as possible your guarantee registration card (delivered with the hydraulic module). If your guarantee registration card is missing you can obtain a copy or record your registration by telephoning the Glow-worm Customer Service number 01773 596510.

- 2 -

The changeover point between the heat pump and the electric heater is managed automatically, depending on the outside and ambient temperatures. Thus, the system always optimises the use of the heat pump with respect to the electric top-up heater.

Avoid programmes with high temperature variations

in the case of power sizing without a signiﬁ cant margin (based on a calculation with a stabilised temperature).

INTRODUCTION

2.1.2 Operating principle of the domestic hot water

system

The domestic hot water heating circuit consists of a heat pump, a 3-way valve and a FLUROCYL hot water tank equipped with an electric heater.

In order to always obtain the best comfort/economy trade-oﬀ , the heat pump and/or the FLUROCYL tank electric heater provide the energy needed to maintain the stored water at the required temperature.

The lower part of the tank is heated 3 times a day by the heat pump. In order to provide maximum economy, the electric heater heats the top part of the tank just to provide the comfort desired by the user.

The lower the hot water temperature setting, the more the heat pump will provide energy and, therefore, more economic operation.
