Service Notification; Set Point At Maximum Volts; On Volts; Off Differential Volts - Lochinvar ARMOR 151 - 801 Service Manual

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 Maximum parameter (H4) is set by parameter H7.
The minimum value is the Set Point at Minimum Volts
setting H6 and the maximum is 190°F (88°C). The default
value is 180°F (82°C).
When programmed for BMS control through the 0 - 10V
BMS input or through ModBus and the BMS Thermostat
Input is set to INACTIVE, parameter H8 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.
When programmed for BMS control through the 0 - 10V
BMS input or through ModBus and the BMS Thermostat
Input is set to INACTIVE, parameter H9 determines how far
below the On Volts setting H8 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 H8.
The default value is 1.0V.
When the water heater control determines that a scheduled
service is due based on days of installation, 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
parameter I1. The time range for this parameter is 0 months
to 36 months. The default time is 0 months.
This feature has been disabled by the manufacturer. To
enable this feature change parameter I1 to the desired time
range.
When the water heater control determines that a scheduled
service is due based on the hours of actual operation, the

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
parameter I3. The range for this parameter is 0 cycles to
100,000 cycles. The default is 50,000 cycles.
Once servicing has been completed, the service notification
counter should be reset. This parameter can be reset by the
installer by accessing parameter I4. Once accessed, press the
