The DIP switch settings on the control are very important and should
be set to the appropriate settings prior to making any adjustments to
the control through the User Interface. The DIP switch settings change
the items that are available to be viewed and/or adjusted in the User
Interface.
The Advanced/Installer DIP switch is used to select which items are
available to be viewed and/or adjusted in the User Interface (see "4.5
View Menu Display Settings" on page 23).
The position of this switch determines at which valve position the control
will close the boiler contact under normal conditions. Refer to section "3.8.2
Boiler Enable" on page 12) for a description of the Boiler Enable DIP.
The Bloc/Station switch is used to select which method the system will
use to adjust supply water temperature. The Mixing Station, Enhanced
Mixing Station, and Diverting Valves use the Three Position Actuator
(Part Number 18003) with a 24V AC floating signal to adjust the water
temperature. It takes 70 seconds for full valve travel. At 50 Hz, it takes
150 seconds to fully open from fully closed. At 60 Hz it takes 120 seconds
to fully open from fully closed. If using Mixing Station, Enhanced Mixing
Station and/or Diverting Valves, set DIP switch to "Station". If using
Viega's 3 or 4 Way Mixing Valves with Viega's Mixing Valve Actuator or
the ProBloc, set DIP switch to "Bloc". The Mixing Valve Actuator takes
102 seconds to fully open from fully closed.
