Overview
SOLA Hydronic boiler control system that provides heat control, flame supervision, circulation pump control, fan control, boiler control and electric ignition function. The SOLA R7910A Hydronic or SOLA R7911 Steam Boiler Control integrates up to fifteen control functions into a single compact device.
Features & Benefits:
Features & Benefits:
- Reduced installation, wiring and maintenance, along with features such as setback, outdoor reset and fan and burner modulation save money and reduce the carbon footprint of the boiler application
- Features such as flame safeguard, pump control, on-board igniter, central heating/domestic hot water high limits, PID load control and operating controls, unlock the door to programming flexibility
- For flexible integrated boiler control SOLA is the most optimal integrated and compact solution for any hydronic and steam boiler application.
