No
No
• Unit is only permitted to only deliver heat.
• Water assumed hot.
• Control algorithm cooling capacity
remains at 0%.
No
Yes
• The controller always uses the
communicated water temperature to
determine whether the unit can heat or
cool as required.
• Entering water temperature sampling not
allowed.
Yes
No
• The controller always uses the local
hardwired entering water temperature to
determine whether the unit can heat or
cool as required.
• Entering water temperature sampling (if
enabled) is invoked as required.
Yes
Yes
• The controller always uses the
communicated water temperature instead
of the local value, to determine whether the
unit can heat or cool as required.
• Entering water temperature sampling not
allowed.
