Boiler Controls
Honeywell Hydronic Panels are capable of managing boilers with DHW priority. The panel features two isolated end
switches labeled Boiler and End Switch for TT outputs to the boiler. Two slide switches are available to provide simple
programing of the end switches to meet the desired application. See the operational matrix below detailing functionality
of the switches.
Additionally, this panel features an end switch for every zone valve, one of which must be closed for pumps and boiler to
be activated.
