QETERM01CE boiler control panels can work individually for only one burner control or with others of the same type, carrying out multiple boiler centralized management. A remote management unit can be connected to a single panel or a series master QETERM01EC panel (maximum 16) can be interconnected through a special bus connection. If a Nereix Master is a constituent part of the system, it can be used for management/remote management of appropriately connected QETERM01EC panels via bus. A QETERM01EC controller can be a master unit for other boiler panels and at the same time slave to a Nereix Master (bus of first and second level). Electronic board key features: - One-stage, two-stage, three-stage burner management - Two-stage progressive burner management - Modulating three point or 0-10 Volt burner control - Temperature regulation of flow delivery temperature with optional external probe - 2 Programmable Outputs (230Vac. / 2 A) configurable to: - Water heater circulation pump management (with thermostat or optional probe) - Boiler circulation pump management - Forward zone system circulation pump management - Mix zone circulation pump management - Cascade collector circulation pump management - Boiler pump input probe - 2 programmable inputs configurable for: - PT1000 probe input - Digital input - Programmable input configurable for: - NTC sensor input - Digital input - Mix, 0-10 Volt command valve management (if there is no adjustable burner with 0 -10 Volt command) - Three point valve management (if a single-stage or modulating burner with 0 -10 control Volt is provided) -Input 0-10 Volt programmable for: - Digital command - Boiler temperature modulation - 0-10 Volt transducer visualization - Cascade management (with function as master or slave) - Pump anti-lock function - Antifreeze protection Communication - Modem connector - USB slot - RS485 for connecting the board to eventual own Master (Boiler Board or Mereix Master) - RS485 connection for board link to eventual own slave (Boiler Board or System Management) Power source 230 Vac
