Boiler Controls - Honeywell HPSR103 Installation Instructions Manual

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 a LOW LIMIT input which must be closed for pumps to be activated. This input comes
with a factory installed jumper for cold start boiler operation when the controlling Aquastat has a HIGH LIMIT only. If the
installed boiler requires warm up time then this jumper should be removed and wired to the boiler.
