Functions
Service Mode Delay
By accessing the Service Maintenance screen from the Settings
menu, the control can be placed in Service Mode. This will
override all other heat demands. The Service Mode allows
the installer to set the unit to any firing rate for the purpose of
combustion analysis. The delay sets the length of time the water
heater will stay in the Service Mode if no keys have been pressed
before going back to its original state. This parameter can only
be changed by the installer by accessing the Service Mode Delay
parameter. The time range of this parameter is 1 to 10 minutes.
The default value is 10 minutes.
DHW Settings
DHW Tank Set Point
By installing a tank sensor, the SMART TOUCH control can
perform the tank thermostat function. The SMART TOUCH
control automatically detects the presence of this sensor, and
generates a DHW call for heat when the tank temperature
drops below the tank set point differential (Tank Set point
Differential parameter), and finishes the call for heat when the
tank temperature reaches tank set point + offset. This parameter
can be changed by the installer by accessing the DHW Tank Set
point parameter. The temperature range of this parameter tank
minimum set point to tank maximum set point. The default
value is 125°F (52°C).
16
Tank Set Point Offset
The tank set point offset measures how far the actual temperature
must go above the set point before the call for heat ends (the
water heater will turn off). This parameter can be changed by
the installer by accessing the Tank Set Point Offset parameter.
The temperature range of this parameter is 0°F (0°C) to 10°F
(30°C). The default value is 4°F (6°C).
Tank Set Point Differential
When a tank sensor is installed, the tank temperature must
drop this amount below the tank set point (DHW Tank Set
point parameter) before the water heater turns back on. The
installer can adjust this setting by accessing the Tank Set point
Differential parameter. The minimum setting is 0° (0°C), and
the maximum is 40°F (22°C). The default setting is 6°F (3°C).
Tank Minimum Set Point
This setting controls the minimum tank set point for the tank
temperature. The installer can adjust this by accessing the Tank
Minimum Set point parameter. The minimum setting is 60°F
(16°C) and the maximum setting is the maximum tank set point
(Tank Maximum Set point parameter). The default value is 60°
(16°C).
Tank Maximum Set Point
This setting controls the maximum tank set point for the tank
temperature. The installer can adjust this by accessing the Tank
Maximum Set point parameter. The minimum setting is the
minimum tank set point (Tank Minimum Set point parameter)
and the maximum setting is 185°F (85°C). The default value is
140°F (60°C).
