The Boiler Control 260 provides partial or full outdoor reset to three (or more) boiler zones. The boiler is operated at the temperature
required in order to satisfy the load.
Heat Source DetailsThe heat source can be either a high mass or low mass non-condensing or low temperature boiler.
Piping DetailsThermostat controlled zone valves are piped into the boiler loop. The boiler pump (P1) provides circulation through these
zones when heat is required.
Boiler DemandWhen heat is required in the boiler zones, the zone valve end switches send a Boiler Demandto the 260. The 260 turnson the boiler pump (P1). The boiler supply water temperature is based on the Characterized Heating Curvesettings. The boiler is fired
to satisfy the required boiler supply water temperature. Whenever the boiler is fired, the 260 aims to increase the boiler supply water
temperature to at least the BOIL MIN setting.
All control functions and specifications are listed in the Product Catalog I 000 and Data Brochure D 260.

The Boiler Control 260 provides partial outdoor reset to three (or more) boiler zones. The 260 also controls the supply of heat to an
indirect fired Domestic Hot Water (DHW) tank. The boiler is operated at the temperature required in order to satisfy the loads.
Heat Source DetailsThe heat source can be either a high mass or low mass non-condensing boiler.
Piping DetailsThermostat controlled zone valves are piped into the boiler loop. The boiler pump (P1) provides circulation through these
zones when heat is required. Heat is supplied to the DHW tank through a DHW valve (V1).
DHW DemandWhen the DHW aquastat (A1) calls for heat, the 260 turns on the boiler pump (P1), opens the DHW valve (V1), and
raises the boiler water temperature to at least 180F (82C).
Boiler DemandWhen heat is required in the boiler zones, the zone valve end switches send a Boiler Demandto the 260. The 260 turnson the boiler pump (P1). The boiler supply water temperature is based on the Characterized Heating Curvesettings. The boiler is fired

Heat Source DetailsThe heat source can be either a high mass or low mass non-condensing or low temperature boiler. If using a lowtemperature boiler, refer to section C3 of the Data Brochure for additional information.

DHW DemandWhen the DHW aquastat (A1) calls for heat, the 260 turns on the DHW pump (P2) and raises the boiler water tempera-
ture to at least 180F (82C). The control can provide DHW priority (refer to section C2 of the Data Brochure) by turning off the boiler
pump (P1). Once the DHW demand is removed, the 260 performs a DHW Post Purgeand possibly a Mixing Purge.

Heat Source DetailsThe heat source can be either a high mass or low mass non-condensing or low temperature boiler. If using a lowtemperature boiler, refer to section C3 of the Data Brochure for additional information.
Piping DetailsThermostat controlled zone pumps are piped into the boiler loop. Heat is supplied to the DHW tank through a DHWpump (P1).
DHW DemandWhen the DHW aquastat (A1) calls for heat, the 260 turns on the DHW pump (P1) and raises the boiler water tempera-
ture to at least 180F (82C). The control can provide DHW priority (refer to section C2 of the Data Brochure) by turning off the Boil P1
contact and not allowing any of the boiler zones to operate. Once the DHW demand is removed, the 260 performs a DHW Post Purgeand possibly a Mixing Purge.
Boiler DemandWhen heat is required in the boiler zones, the zone pump relays send a Boiler Demandto the 260. The boiler supply
water temperature is based on the Characterized Heating Curvesettings. The boiler is fired to satisfy the required boiler supply water
temperature. Whenever the boiler is fired, the 260 aims to increase the boiler supply water temperature to at least the BOIL MIN setting.
