One circle secondary thermostatic heating system

Pump unit with thermostatic mixing valve

Heating circuit supplier pump unit
Advangates:

• Space-saving, compact design
• Insulated, aesthetic
• Quick and easy assembling
• Mechanic friend therefore is more economical to build up
• Plannable mechanic costs
• Adjustable heating water temperature per heating circuit
• Reasonable price/value rate
• Long lifetime for the best quality components

DN20 pump units can be connected to heating systems with powers up to 22kW, with a very low energy consumption assured by high efficiency synchronous circulating
pumps.

Dimensions: 180x302x142mm (EPP insulation box)
Centre distance: 90mm
Especially suitable to manage medium-low powers in small rooms, thanks
to its centre distance of only 90 mm.

For power up to 22 kW (with Δt 20 K)
Maximum flow 1000 l/h.
Kvs value: 2,0
PN 10, max temperature 110°C (unit without pump).
Connections:

• 3/4” Male with swivel tang to the heat source or to the distributor.
• 3/4” Female to the user.

The unit for 1/2” (130 mm) circulating pumps consists of:

Supply:

• Connection.
• Thermostatic mixing valve with temperature setting range, models F1 and F2.
• High efficiency synchronous pre-wired circulating pump (for the models that include it).
• Flanged ball valve supplied with in-handle thermometer (coded red, range 0°C-120°C).
  

Return:

• Flanged ball valve with non return valve 20 mbar (which can be excluded by rotating the handle by 45°) supplied with in-handle thermometer (coded blue; 0°C-120°C).
• “T” Connection for mixing valve.
• Connection.

Euroster 11M

Electronic, programmable controller designed for control of a three-way valve with actuator and CH circulation pump. It automatically maintains a constant temperature at a preset level or ensures a proper temperature of water in return piping in a CH system with coal-fired boiler. Possibility to connect a room thermostat. E11M controller is equipped with an AntiStop function which prevents seizure of the idle pump and valve rotor.

Controller function

• keeps constant water temperature: in the central heating
  circuit or in boiler return
• possibility of connecting room regulator
• Anti-Stop function to protect pumps and valve against
  stoppage
• frost protection
• pump operation test
• temperature reading correction

EUROSTER 11M operates in one of the two modes: heating medium temperature regulation (e.g. in floor heating) or return temperature stabilization. Operation mode is changed when restoring factory settings, provided for each of the modes.

Set 1: intended for system with heating medium temperature regulation

Set 2 intended for system with return temperature regulation
