heat. By default, the auxiliary heat is disabled. When auxiliary heat is
enabled, the following parameters are used to configure the
operation of the auxiliary heat:
Configuration Menu.
- Available Stages. Defines how many stages of auxiliary heat
a system has.
- First Supply Heat. If the setting for Auxiliary heat is 1 or 2,
then the first system to supply heat must be defined as
either: Heat Pump or Aux. Heat.
o Fan Configuration. Select between Electric (Fan on)
or Furnace (Fan off) option. If you select Electric
option, define:
§ Fan Delay (s). Defines the delay time (in
seconds) to turn off the fan when there is no
demand from the Auxiliary Heater. Possible
values are 0, 45, 60 and 120 seconds.
First Stage Menu.
- First Stage Differential. Temperature that the system has to
surpass to activate the first stage of auxiliary heat. Values: 2
to 10˚F/1 to 5˚C in increments of 1˚F/0.5˚C. By default,
2˚F/1˚C.
- First Stage Hysteresis. Defines the hysteresis for the
operation of the first stage. Values: 1-2˚F/0.5-1˚C in
increments of 1˚F/0.5˚C. By default, 1˚F/0.5˚C.
- Min. Time Exhausted. Minimum time that the Heat Pump
must be active before the first stage of auxiliary heat can be
activated. Possible values are 0, 45, 60 and 120 minutes. By
default, 45 minutes.
Second Stage Menu.
- Second Stage differential. Temperature that the system
has to surpass to activate the second stage of auxiliary heat.
Values: 2 to 10˚F/1 to 5˚C in increments of 1˚F/0.5˚C. By
default, F/1˚C.
- Second Stage Hysteresis. Defines the hysteresis for the
operation of the second stage. Values: 1-2˚F/0.5-1˚C in
increments of 1˚F/0.5˚C. By default, 1˚F/0.5˚C.
- Min. Time Exhausted. Minimum time that the first stage
must be active before the second stage of auxiliary heat can
be activated. Possible values are 0, 45, 60 and 120 minutes.
By default, 45 minutes.
Note: if the auxiliary heat is
electrical and the installation is
heat pump type, then the first one
to supply heat must be Heat Pump
in the DZK master system.
