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.
EN
- 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
i
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.

Application conditions
INTRODUCTION
- The Systempro control unit manages the Domestic Hot Water
cylinder.
- 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.
Use 0.75 mm² section cables for the electrical
e
connections to the control unit.
