Field of application
Pump group SIMPLE is used in high-temperature heating systems when there is a need to warm up low-temperature
heating system - radiant heating (floor / wall heating). The set consists of mixing valve with thermostatic head,
non-return valve, spacer, immersion sleeve, contact control thermostat, two holland connectors and two ball valves
with holland conectors. Mixing set controlls secundary heating circuit by which it controlls the temperature in room
(depending on the needs). Supply flow temperature can be regulated to a constant value or according to the needs
of the user.
Assembly
Pump group SIMPLE for underoor heating can be mounted directly on high – temperature heating system. The
mounting position is arbitrary. By using the connectors with free moving nut we can mount the mixing set directly to
the distributors for oor heating systems. Connections on the pump are not completely screwed in, as the installer
can adjust the position of the pump to its needs. After assembly, the installer must check connections on the pump
for water tightness. In case there are impurities in the medium (hard water, dust, etc.) it must be installed a lter,
otherwise impurities may damage the valve seals. Included contact thermostat Afriso GAT / 7HC protects the system
from overheating. Authorized installer set the max. temperature on the outlet and mounts the contact thermostat on
the upper mixing unit (position 6 on components picture, page 3).
Brass
HERZ use top-quality brass that responds to the latest European norms DIN EN 12164 and DIN EN 12165. Parts of
the pump group Simple are made from brass due to its good strength and excellent corrosion resistance.
Pursuant to Article 33 of the REACH Regulation (EC No. 1907/2006), we are obliged to point out that the material
lead is listed on the SVHC list and that all brass components manufactured in our products exceed 0.1 % (w / w) lead
(CAS: 7439-92-1 / EINECS: 231-100-4). Since lead is a component part of an alloy, actual exposure is not possible
and therefore no additional information on safe use is necessary.

system - radiant heating (floor / wall heating). The set consists of mixing valve with thermostatic head, non-return
valve, spacer, immersion sleeve, contact control thermostat, two holland connectors and two ball valves with holland

is arbitrary. By using the connectors with free moving nut we can mount the mixing set directly to the distributors for
floor heating systems. Connections on the pump are not completely screwed in, as the installer can adjust the position
of the pump to its needs. After assembly, the installer must check connections on the pump for water tightness. In case
there are impurities in the medium (hard water, dust, etc.) it must be installed a filter, otherwise impurities may damage
the valve seals. Included contact thermostat Afriso GAT / 7HC protects the system from overheating. Authorized installer
set the max. temperature on the outlet and mounts the contact thermostat on the upper mixing unit (position 6 on
components picture, page 3).
Brass
HERZ use top-quality brass that responds to the latest European norms DIN EN 12164 and DIN EN 12165. Housings of
ball valves are made from brass due to its good strength, excellent corrosion resistance and variety of other properties.

Maintaince
According to EN 806-5 (point 6. Operation) valves should always be in their fully opened or closed position and
actuated at regular intervals to ensure they remain operational. Therefore HERZ Ball valves should be closed and
opened periodically at least twice a year. This prevents the ball valve from blocking, reduces sediment deposition and
reduces the possibility of corrosion inside the valve.
Disposal instructions
The disposal of HERZ - Pump group Simple must not endanger the health or the environment. National legal
regulations for proper disposal of the HERZ - Pump group Simple have to been followed.

the EPDM seals. Please refer to manufacturers documentation when using ethylene glycol products for frost and
corrosion protection.

Electrical connection
May only be installed by qualied technicians.
- The current type and voltage must correspond to the specications on the rating plate.
- Maximum back-up fuse: 10 A, slow-blow.
- Only operate the pump with sinusoidal AC voltage.
- Note the switching frequency:
• On/off switching operations via mains voltage ≤ 100/24 h.
• ≤ 20/h for a switching frequency of 1 min. between switching on/off via mains voltage.
- The electrical connection must be made via a xed connecting cable equipped with a connector device or an
all-pole switch with a contact opening width of at least 3 mm.
- Use a connecting cable with sufcient outer diameter (e.g. H05VV-F3G1.5) to protect against leaking water
and to ensure strain relief on the threaded cable connection.
- Use a heat-resistant connecting cable where uid temperatures exceed 90 °C.
- Ensure that the connecting cable does not make contact with either the pipes or the pump.
Connecting the mains cable
- Cable assignment:
• 1 yellow/green: PE
• 2 blue: N
• 3 brown: L
- Press down the locking button of the 3-pin pump plug and connect the
plug to the plug connection of the control module until it snaps into place.
Intended use
High-efciency circulators in the Wilo-Para series are exclusively intended for circulating uids in hot-water heating
systems and similar systems with constantly changing volume ows.
Permitted uids:
- Heating water according to VDI 2035 (CH: SWKI BT 102-01) or ÖNORM H 5195.
- Water-glycol mixtures* with a maximum of 50% glycol.
*Glycol has a higher viscosity than water. If admixtures of glycol are used, the pumping data of the pump must be
corrected to match the mixing ratio. Intended use includes observing these instructions and the specications and
markings on the pump.
