Overview:
The SR506-5 is a six zone switching relay that can have up to 6 thermostats
connected and will operate up to 6 zone circulators, plus 2 auxiliary outputs (AUX) to
control circulators; like boiler and primary loops.
The SR506-5 has a priority zone option, allowing zone 1 to operate and deactivate
zones 2 through 6 during a priority call; this is ideal for when using an indirect water
heater.
The SR506-5 includes timing options for Post Purge, Pump Exercise and Priority
Protection. The SR506-5 includes an energy saving program that can adjust the
temperature of a modulating-condensing boiler or conventual On/Off boiler to
increase the comfort level and use less fuel, without the need to install an outdoor
sensor.
