5-3.10 To Change DHW Loop P-I-D Parameters
ConfigureDHW – Domestic Hot Water ConfigurationP-Gain Textbox (Default: 50)
ConfigureDHW – Domestic Hot Water ConfigurationI-Gain Textbox (Default: 50)
ConfigureDHW – Domestic Hot Water ConfigurationD-Gain Textbox (Default: 0)
x Type in desired number between 0 to 400
P gain applied to the proportional term of the PID equation for the DHW loop.
I gain applied to the Integral term of the PID equation for the DHW loop.
D gain applied to the Differential term of the PID equation for the DHW loop.
5-3.11 To Change DHW Modulation Sensor
ConfigureDHW – Domestic Hot Water ConfigurationModulation Sensor Textbox
(DHW Mode Default: DHW Sensor, Com Mode Default: Outlet Sensor (S1))
x Select DHW sensor for DHW modulation sensor
x Select Outlet sensor for DHW modulation sensor
x Select Inlet sensor for DHW modulation sensor
x Select Auto DHW (S6) of Inlet (S1) for Inlet modulation sensor when DHW switch is enabled
x Select Auto DHW (S6) of Outlet (S1) for outlet modulation sensor when DHW switch is enabled
5-3.12 To Change DHW Loop Priority Versus LL
ConfigureDHW – Domestic Hot Water ConfigurationDHW Priority vs Lead Lag Textbox (Default: DHW>LL)
x Select LL>DHW for no priority over LL loop
x Select DHW>LL for priority over LL loop
This parameters determines the priority of DHW vs. the LL call-for heat, when both of these are enabled and active. (If
DHW has a lower priority, it may be boosted to the highest priority temporarily via the DHW Priority Time parameter.)
5-4 Modulation Related Configuration
5-4.1 To Change CH Loop Maximum Modulation Rate
ConfigureModulation ConfigurationCH Maximum Modulation Rate Textbox
(Default: Varies based on model)
x Type in RPM rate between light off rate and maximum modulation rate
Provides the upper limit of modulation when firing for CH or LL slave mode.
5-4.2 To Change DHW Loop Maximum Modulation Rate
ConfigureModulation ConfigurationDHW Maximum Modulation Rate Textbox
(Default: Varies based on model)
x Type in RPM rate between light off rate and maximum modulation rate
Provides the upper limit of modulation when firing for DHW.
5-4.3 To Change CH Loop Forced Rate Time
ConfigureModulation ConfigurationCH Forced Rate Time Textbox (Default: 0m10s)
x Type in desired time between 0 to 5 minutes
For CH demand, if the CH forced rate time is non-zero, then the firing rate will be held at the rate specified here during
that time. This parameter is also needed as the starting point for Slow State, even if the forced rate time is zero.
5-4.4 To Change CH Loop Forced Rate
ConfigureModulation ConfigurationCH Forced Rate Textbox (Default: Varies based on model)
x Type in RPM rate between light off rate and maximum modulation rate
For CH demand, if this time is non-zero then, upon entry to Run, the firing rate will be held at the CH forced rate.
