REV 1.1 FIII SERIES CONTROL TYPE CALIBRATE temperature. If the HEADER sensor is used (TYPEZ), that boiler performs the tasks of the MASTER boiler. If the HEADER sensor is set to NONE, its function is the MEMBER. The remaining (2) sensors perform as user selections and provide functions such as: Combustion Air Proving. There are (4) sensor types: NONE = don not use this sensor TYPEZ = 10k thermistor TE6000 = 1k Nickel RTD ON/OFF = 5 volts supplied out to detect a contact/switch closure. Placing a precision 10k (TYPEZ) or 1k (TE6000) precision resistor across the sensor input selected allows calibration of the sensor input. PASSWORD AAAAAA Provides a limited access for security, though restoring system defaults will reset the password to the value “AAAAAA” COMMUNICATIONS MODEM INSTALLED NO Modem support is not available currently with this release. LOAD DEFAULTS FACTORY CAL? Selecting YES will load just the factory calibration values: MIN, MAX and IGNITION. FACTORY RESET? NO Selecting YES will load all factory defaults except the Calibration values. SYSTEM FACTORY TEST Used by factory to check analog and binary inputs. LOAD FIRMWARE NO Answering YES deletes the Firmware and allows a firmware update. APPLICATION HEAT This is the type of heating application that this boiler will perform. If the boiler is to be used for heating of a building, HEAT is selected. If it is to be used to heat domestic hot water DHW, select DHW. The result of setting is so that HEAT or DHW will produce the correct display terms. These can be observed when cycling through menus or viewing temperatures on the status screens. Page 20
REV 1.1 FIII SERIES CONTROL MODBUS Communications The FIII-series control can be controlled using Modbus commands to Enable/Disable the boiler/system. A connection to the Console Modbus Port on the Communications board is required. The Master Boiler assumes the role of MEMBER, RTU, 192Kb, 8 bits, Even Parity, 1 stop bit, when connected to a BMS (Building Management System). The Member Boilers should not be connected to a BMS system other than to view Read Only addresses. Modbus Holding (Read/Write) Registers Address Data Type Description Valid Values/Range 0 Unsigned Boiler/System Enable/Disable 0 = Disabled/Off 1 = Enabled/On 1 Unsigned System Setpoint Timer (1) 0 – 65535 seconds 2 Unsigned System Setpoint (1) 40°F – 220 °F 3 Unsigned Outdoor Air Reset Enable/Disable 0 = Disabled/Off 1 = Enabled/On 4 Unsigned Outdoor Air Setpoint 40°F - 100 °F 5 Unsigned Water Temperature at High Outside Air 60°F - 150 °F 6 Unsigned High Outside Air Temperature 50°F - 90 °F 7 Unsigned Water Temperature at Low Outside Air 70°F - 220 °F 8 Signed Low Outside Air Temperature -35°F - 40 °F 9 Unsigned Set Clock – Month (2) 0 – 11 10 Unsigned Set Clock – Day of Month (2) 1 – 31 11 Unsigned Set Clock – Year (2) 0 – 99 12 Unsigned Set Clock – Hours (2) 0 – 23 13 Unsigned Set Clock – Minutes (2) 0 – 59 14 Unsigned Set Clock – Seconds (2) 0 – 59 15 Unsigned Set Clock – Day of Week (2) 1 – Monday 7 – Sunday 16 Unsigned Set Clock – After the Set Clock Registers listed above have been written, a 1 must be written to this location to set the clock. (2) 1 (1) The system setpoint timer and system setpoint work in tandem to externally control (i.e. a BMS - building management system) the operating setpoint. The setpoint (countdown) timer should be loaded with a timeout value (in seconds) prior to writing the system setpoint. When the timer reaches zero, the control assumes that the BMS is no longer operating and the local setpoint (saved on the control) is reloaded. This is a failsafe feature used to help safeguard the system in case of BMS failure. If the setpoint timer is not written, a default timeout value of 60 seconds is assumed. (2) To write the system clock, registers 9 – 15 must first be loaded with the correct date and time. Then, a 1 must be written to register 16 to write the date and time to the system clock. Page 21
