Rate at Maximum Volts
When programmed for BMS control through the 0 -
10V BMS input or through ModBus and the BMS Type
is programmed as POWER, the modulation percentage
represented by the Volts at Maximum parameter is set by
the Rate at Maximum Volts parameter. The minimum value
is the Rate at Minimum Volts setting and the maximum is
100%. The default value is 100%.
Set Point at Minimum Volts
When programmed for BMS control through the 0 - 10V
BMS input or through ModBus and the BMS Type is
programmed as SETPOINT, the set point represented by
the Volts at Minimum parameter is set by the Set Point at
Maximum Volts parameter. The minimum value is 32°F
(0°C) and the maximum is the Set Point at Maximum Volts
setting. The default value is 70°F (21°C).
Set Point at Maximum Volts

the Volts at Maximum parameter is set by the Set Point at
Maximum Volts parameter. The minimum value is the Set
Point at Minimum Volts setting and the maximum is 190°F
(88°C). The default value is 180°F (82°C).
On Volts
When programmed for BMS control through the 0 - 10V
BMS input or through ModBus and the BMS Thermostat
Input is set to INACTIVE, the On Volts parameter determines
the 0 - 10V BMS input voltage at which the water heater is
enabled. The minimum value is 0.5V and the maximum is
10.0V. The default value is 2.0V.
Off Differential Volts
When programmed for BMS control through the 0 - 10V
BMS input or through ModBus and the BMS Thermostat
Input is set to INACTIVE, the Off Differential Volts parameter
determines how far below the On Volts setting the 0 - 10V
BMS input voltage must be in order to disable the water
heater. The minimum value is 0.2V and the maximum is the
On Volts setting. The default value is 1.0V.
Service Notification
Service Notification in Months
When the water heater control determines that a scheduled

service is due based on the number of water heater cycles, the
water heater display will alternate the standard water heater
display text with the message SERVICE DUE every 5 seconds.
This parameter is adjustable by the installer by accessing
the Service Notification Cycles parameter. The range for this
parameter is 0 cycles to 100,000 cycles. The default is 50,000
cycles.
