Service/Setup Parameters Screen:
1 Service
The Service / Setup Screen allows access to 10 parameters.
Those parameters are as follows:
• Demand Configuration - Sets the configuration of the
control modules inside the water heater. The
configuration selections are:
Demand Configuration 1: Cascade Set Point Thermostat
based - the control modulates the water heater based on the
user set point and the temperature of the tank sensor.
Demand Configuration 2: Cascade BMS Thermostat
based - a 0 - 10Vdc signal is provided to the water heater
to control either the set point or the modulation of the
water heater.
Demand Configuration 3: Cascade BMS Voltage based - a
0 - 10Vdc signal is provided to the water heater to control
either set point or modulation. A minimum voltage signal is
required to initiate a call for heat.
Demand Configuration 4: Cascade Set Point Modbus
Thermostat based - the control modulates the water
heater based on the tank set point and the temperature of the
tank sensor. An enable signal is provided by writing
to the holding registers on the Modbus communication
board.
Demand Configuration 5: Cascade Modbus BMS
Thermostat based - a 0 - 10V dc signal is provided to the
water heater to control either the set point or the modulation
of the water heater. An enable signal and an equivalent 0 -
10V signal is provided by writing to the holding registers on
the Modbus communication board.
Demand Configuration 6: Cascade Modbus BMS Voltage
based on a 0 - 10V dc signal is provided to the water heater to
control either set point or modulation. An equivalent 0 -
10V dc signal is provided by writing to the holding registers
on the Modbus communication board.
When any of these BMS configurations are selected, additional
parameters for BMS operation will have to be adjusted. Reference
the BMS parameters on pages 23 and 24 for information
regarding adjusting these parameters. There are three (3) other
configuration selections that are possible, however, they must
NOT be used on the Armor X2 water heater.
This parameter can only be changed by the installer. The default
configuration is Cascade Set Point Thermostat based.
• Service Notification Time - When the water heater
determines that a scheduled service is due based on days of
installation, the Service Needed screen will appear. This
parameter can only be changed by the installer. The
adjustment range for this parameter is 0 months to 36
months. The default time is 12 months.
• Service Notification Running Hours - When the water
heater determines that a scheduled service is due based on the
hours of actual operation. This parameter can only be
changed by the installer. The adjustment range for this
parameter is 0 hours to 100,000 hours. The default time is
10,000 hours.
• Service Notification Cycles - When the water heater
determines that a scheduled service is due based on the
number of water heater cycles, the Service Needed screen will
appear. This parameter can only be changed by the
installer. The range for this parameter is 0 cycles to 100,000
cycles. The default is 10,000 cycles.
