1 Service 18 SH Maximum setpoint (boiler only) The SH maximum setpoint sets the maximum water temperature setpoint that can be used for space heating. The user or installer will not be able to program the control with a higher SH setpoint. The temperature range of this parameter is 32°F (0°C) to 230°F (110°C).
1 Service (continued) 19 Copper-fin II/IIE Boiler and Water Heater Service Manual DHW/SH switching time (boiler only) The time that the SMART SYSTEM control services a DHW demand before returning to the SH demand is set by this parameter. The range of this parameter is 0 to 240 minutes.
1 Service 20 Maximum SH setpoint When the outdoor temperature drops to its minimum setting (F1) the water temperature setpoint will be at this value, if the SH setpoint is set higher (FIG. 1-1). The temperature range of this parameter is 32°F (0°C) to 248°F (120°C).
1 Service (continued) 21 Outdoor air shutdown differential The outdoor air shutdown differential parameter is the number of degrees below parameter F5 the outdoor air temperature must go before the unit will respond to a SH demand. The temperature range of this parameter is 0°F (0°C) to 90°F (50°C).
Control modes SH controlling sensor (boiler only) The SH controlling sensor parameter selects the sensor the control will use to regulate the boiler firing rate.
1 Service (continued) 23 Cascade Boiler address The boiler designated as the Leader needs to be programmed with address 0. All the Member boilers require addresses from 1 to 7, and the addresses must be different for each Member. The addresses can be in any order, regardless of the order in which the units are wired together.
