The electronic circulator pump OPTI ECO 25-40/180 (5-22W) features energy-saving characteristics and is designed for forced circulation in heating systems. It can be used in single and double piping as well as in underfloor heating installations. It is equipped with a system that automatically adjusts the pump characteristics to the operating installation.

Features:

• Easy installation and operation (external connector for pump connection).
• Universal design suitable for all residential installations.
• Low noise level.
• Low energy efficiency index EEI <0.20.
• Excessive quality.

The electronic circulator pump OPTI ECO 25-60/130 (5-45W) combines similar features but also offers additional functions. It provides energy consumption indication [W] and head indication [m], 8 functional modes, as well as night operation. It is suitable for:

• Constant temperature heating system with variable flow.
• Variable temperature heating pipe system.
• Night operation heating system.
• Air conditioning system.
• Central heating system for homes and household hot water system.

The pump includes 8 functional modes:

• AUTO - automatic adjustment of pressure and pump performance according to system demand.
• PP2 - higher proportional pressure-capacity characteristic.
• PP1 - lower proportional pressure-capacity characteristic.
• CP2 - higher characteristic level that keeps the pump pressure constant.
• CP1 - lower characteristic level, maintaining constant pressure.
• I, II, III - manual modes that maintain constant height.

The pump has a night operation mode, activated when a temperature drop of 0.1 degrees C/min is detected for approximately 2 hours.

PARAMETERS: Energy class A, 5W - 45W flow/min: 55l, Flange diameter: 1 1/2", Maximum operating pressure: 10 bar, Head: up to 6 m, Protection class: IP44, Pump volume: less than 43dB, Maximum fluid temperature: 110 degrees C.
