Maximum Input when Responding to a Call for DHW – Parameters 15/16 define the maximum fan speed (and
therefore the maximum firing rate) when the boiler is responding to a call for heat from the DHW thermostat.
Parameter 15 defines the “thousands” and “hundreds” places of this fan speed and Parameter 16 defines the “tens”
and “ones” places. For example, if Parameter 15 is set to “42” and Parameter 16 is set to “51”, the maximum fan
speed when responding to a call for DHW will be 4251 RPM.
The maximum DHW fan speed is factory set below the maximum central heating fan speed so as to permit the
use of smaller sized piping and pumps (see Table 8.9). If adequate boiler water flow is provided through the indi
-
rect water heater loop, the DHW maximum firing rate can be set to full input (defined by parameters 13/14).
Although Parameters 2 and 3 should be left at the factory settings of “ON”, it is relatively easy to change them
by accident (pushing and holding the “+” or “-” key while the boiler is in standby mode will change them). If the
boiler does not respond to a call from one or both thermostats, verify that Parameters 2 and 3 are both “ON”.
E. Communication, Fan Speed and Error Modes
In addition to providing access to all field adjustable parameters, entering the access code also provides access to
three additional mode menus using the boiler keypad. These are shown in Figure A.1:
1) Communication Mode
- This mode does not currently have any function.
2) Fan Speed Mode
- Allows the user to view the blower fan speed (firing rate is determined by fan speed).
3) Error Mode - Pressing STEP while in Error mode allows the user to view the last lockout error code that has
occurred along with 5 other values which display the boiler status at the time of the last error. See Table A.4.
