Description
The BT1050 is a timer for the control of a bottom blowdown valve.
It allows the bottom blowdown valve to open, removing
precipitated solids that could otherwise build up and eventually
cause damage.
The BT1050 has three timers. These allow different blowdown
cycle times and durations to be set, for example, MON - FRI.
Up to three blowdown cycles can be selected in one day. The
timers can also be used to prioritise boiler blowdown cycles.
The product can be panel, DIN rail or chassis mounted and is
powered by a 110 to 240 Vac at 50 / 60Hz mains supply.
The front panel has an LCD graphic display and five-button
keypad.
A test function provides the operator with a diagnostic tool.
The BT1050 can communicate via an infrared link between
adjacent units. It can be designated as either a slave or a master
unit, and connected to a two or four wire EIA / TIA-485 multi-drop
network.
Up to nine BT1050 (or BT1000) units can be installed and linked
for multi-boiler installations.
