2-way pump unit with 3-way mixing valve and electronic circulating pump. Built-in climatic controller for complex installations
Climatic regulation pump unit for control of 1 or 2 circuits and request for energy (heat source), DHW production or solar circuit management, cooling system management. It is possible to connect one each other several hydraulic modules via CAN-Bus and to connect the new °Caleon room thermostat. The pump unit, by acquiring the value of the outside temperature, settles the right supply temperature of the installation on the base of the set climatic curve. The unit is supplied completely assembled and tested. No wiring operations are needed: the circulating pump, the servomotor of mixing valve and the climatic controller are pre-wired for a pratical and effective installation.

  • 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.
  • Isolating flanged ball valve with unions.
  • Connection.

Centre distance 125 mm. EPP insulation box (Measurements: 250x466x215 mm).
A special back plate fixes the unit to the insulation box and it allows a quick fitting to the wall or to the solar cylinder.

PN 6, max temperature 110°C.
(max. 40°C ambient temperature and 95°C fluid temperature).
External connections:  1” Female.

FIELD OF UTILIZATION:
For power up to 35 kW (with
Δt 20 K) and maximum flow 1500 l/h.
Kvs Value: 6,0.
Approximate data calculated with a Wilo Yonos PICO 25/1-6 circulating pump (6 m nominal lifting power).
For power up to 20 kW (with Δt 8 K) and maximum flow 2150 l/h.
Kvs Value: 6,0.
Approximate data calculated with a Wilo Yonos PICO 25-1-8 circulating pump (8 m nominal lifting power).
For an accurate measuring or higher flow, please refer to the curves of the circulating pumps (constant Δp and variable Δp).


MIXING VALVE WITH SERVOMOTOR

3-way mixing valve with bi-directional servomotor with an operating range of 90°; led of activity in opening and closing mode. Selector for manual working with the indicator handwheel. A special connector allows to replace the servomotor in case of failure or bad working without having to operate on electric wires.
Kvs Value of the mixing valve: 10,0.

 

 
 


CIRCULATING PUMP

Wilo Yonos PICO 25/1-6 and Yonos PICO 25/1-8.
High efficiency circulating pumps with electronically commutated motor. Integrated differential pressure control: constant Δp or variable Δp.

  • Constant Δp: for heating circuits with a stable pressure drop (i.g. underfloor heating) or plants where the pressure drop of pipes is negligible in comparison with the pressure drop of the thermostatic radiator valves, or where indipendently from open thermostatic radiator valves, same differential pressure is requested.
  • Variable Δp: in order to achieve the max energy saving and noise reduction. It is recommended in plants where the pressure drop of the pipes is higher than the pressure drops of the regulating valves, or more simply, when the requested differential pressure is decreasing when the flow comes down.

In compliance with European Directive 2009/125/CE. Low energy consumption from 4 W to 40 W (Wilo Yonos PICO 25/1-6) and from 4 W to 75 W (Wilo Yonos PICO 25/1-8) at max flow. Automatic air vent program. Which allows a quick elimination of air during the first start of the plant. Molex automatic connector, which allows to replace the circulating pump in case of failure or bad working, without having to operate on electric wires.

CLIMATIC CONTROLLER CLIMA L

Climatic controller with wide LCD display to manage complex installations.

  • Pictogram of selected hydraulic circuit with indication of the relays activity status: circulators, valves (mixing or diverting) and request of energy source.
  • CAN-Bus connection to connect several pump units.
  • Possibility of remote control and data backup thanks to the Connect system (the special  Datalogger, not included, is necessary).
  • Visualization of temperature of sensors. Active modality of working: day or night.
  • Pre-setting of characteristic curves (1 or 2 circuits) with linear slope or broken and related day-night correctors.
  • Protection function: anti-blockage circulating pump, anti-frost control, min and max supply temperature.
  • Daily up to three time bands can be set up: active in day modality or reduction night.
  • Data memory with statistical analisys of the working of the plant (temperatures, working times, error messages, etc).
  • Room thermostat °Caleon (optional). Elegant climatic control unit equipped with a touch-screen color display. It allows an easy remote management of the heating system.Operation modality: Normal, Turbo, Eco and Off with specific temperature set-point. Holiday program. 8 Selectable daily heating time slot.
  • Cooling mode with thermostat °Caleon Clima.

The controller is supplied pre-wired with following sensors (PT1000):

  • power cable with Schuko plug;
  • cable for controlling circulating pump with Molex connector;
  • cable for controlling servomotor with automatic connector PR120;
  • temperature sensor for mixed circuit TR/S1,5;
  • pre-wired power box for the relay R4 management;
  • pre-wired sensor box for connecting the 5 sensors of the system, the room thermostat °Caleon (1 or 2 depending on the hydraulic diagram selected) and the 2 additional 0/10V free outputs. One of these outputs can be transformed into open or closed contact thanks to a relay built in the sensor box (up to 6A). All cabling is thus eased without having to access the control unit;
  • outside temperature sensor TA/55.

For a fast and easy connection of the temperature sensors you do not have to handle the controller, it is enough to plug the cables in the automatic connectors of the sensor box.

 
Measuring and check of a DN25 system

  Clicking on the icon at side it is possible to download an Excel file dealing with the measuring and the check of a DN25 pump unit; it is possible to select the model and the working parameters, so getting a check of the power and of the residual lifting power. In case of underfloor heating system the surface that can be managed is approximately calculated. Changing the starting data it is possible to simulate different employment situations and to make your considerations.
