Circulation pumps
DHW Pump Delay
The DHW pump delay parameter sets the length of time the
DHW pump (if connected) will run after a DHW demand has
been satisfied. This parameter is adjustable by the installer by
accessing the DHW Pump Delay parameter. The time range for
this parameter is 10 seconds to 40 minutes. The default time
is 1 minute.
DHW Pump Anti-Seize Delay
If the water heater pump does not run for 24 hours, it will be
turned on briefly to prevent it from seizing. The length of
time it runs is determined by the DHW Pump Anti-Seize Delay
parameter. The range of this setting is 0 seconds to 50 minutes.
The default setting is 20 seconds.
BMS
BMS Type
When programmed for BMS control through the 0 - 10V BMS
input or through ModBus, the 0 - 10V signal can be interpreted
as either a modulation command or a set point. When the
BMS Type parameter is set to POWER, the 0 - 10V signal will
control the modulation. When set to SETPOINT, the 0 - 10V
signal will control the tank set point. The default setting is
SETPOINT.
Volts at Minimum
When programmed for BMS control through the 0 - 10V BMS
input or through ModBus, the Volts at Minimum parameter
should be set to the minimum voltage signal sent to the
SMART TOUCH control. The range of this parameter is 0.0V
to the Volts at Maximum value. The default setting is 2.0V.
Volts at Maximum
When programmed for BMS control through the 0 - 10V BMS
input or through ModBus, the Volts at Maximum parameter
should be set to the maximum voltage signal sent to the
SMART TOUCH control. The range of this parameter is the
Volts at Minimum value to 10.0V. The default value is 10.0V.
Rate at Minimum 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 Minimum parameter is set by the Rate at Minimum Volts
parameter. The minimum value is 0% and the maximum is
the Rate at Maximum Volts setting. The default value is 20%.
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
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 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 months of installation, the water
heater display will alternate the standard water heater
display text on the home screen with the message SERVICE
DUE every 5 seconds. This parameter is adjustable by the
installer by accessing the Service Notification in Months
parameter. The time range for this parameter is 0 months to
100 months. The default time is 12 months.
This feature has been disabled by the manufacturer. To
enable this feature update the Service Notification parameter
to the desired time range.
This feature has been disabled by the manufacturer. To
enable this feature change the Service Notification in Months
parameter to the desired time range.
