Control unit ST-24 for circulation pump and fan with speed controller (DE.150)

Functions implemented by the control unit

• Fan control
• Control of the central heating pump

Equipment of the control unit

• LED display
• Heating temperature sensor
• is equipped with a temperature fuse (thermal fuse).
• Housing for mounting on the boiler, made of high-quality, heat- and frost-resistant materials

Technical data:

• Supply V 230V/50Hz +/-10%
• Maximum power consumption of the control unit W 4
• Ambient temperature OC 5÷50
• Maximum load on the CH pump output A 0.5
• Maximum load on the fan output A 0.6
• Accuracy of measurement OC 1
• Range of temperature settings OC 45÷80*
