Anti-Cycling
Anti-Cycling Time
Once a DHW demand has been satisfied, a set amount of time
must elapse before the control will respond to a new DHW
demand. The control will block the new heat demand and anti-
cycling will be shown in the display until the time has elapsed
or the water temperature drops below the Anti-Cycling Override
Differential parameter. This parameter can be changed by the
installer by accessing the Anti-Cycling Time parameter. The
time range for this parameter is 1 minute to 10 minutes. The
default value is 1 minute.
Anti-Cycling Override Differential
The control will bypass the anti-cycling time if the inlet water
temperature drops too much. The control will use the inlet
water temperature the water heater was at when it shut off as
the starting point. If the inlet temperature drops below the
temperature parameter the control will abort anti-cycling and
allow the water heater to fire. This parameter can be changed by
the installer by accessing the Anti-Cycling Override Differential
parameter. The temperature range of this parameter is 0°F (0°C)
to 54°F (30°C). The default value is 10°F (6°C).
Figure 1-4 Ramp Delay Interval
Ramp Delay (Enable / Disable)
This parameter allows the installer to enable or disable the
DHW ramp delay. The default setting is disabled.
Ramp Settings
The SMART TOUCH control can be programmed to limit
the firing rate for a fixed period of time at the start of a DHW
demand. There are six (6) possible limits, each with their own
time delay. The first limit applies as soon as the burner starts.
Once its time delay expires, the second limit is applied and its
timer begins. The control steps through these limits until the
6th (sixth) limit expires. Note, however, that the 6th limit will
also limit the rate for the rest of that heat demand. The installer
can adjust the firing limits and time delays by accessing the
Ramp Delay Screen. The screen will show the step number, the
time delay for that step and the limit value corresponding with
that step.
