SECTION 2 – INSTALLATION
2.15 BOILER PUMP RELAY
The Benchmark Platinum's power panel includes a secondary output board with a pump relay
that is designed to operate a boiler pump. This relay provides 120VAC with a maximum pilot
duty of 3 amps. If the pump power requirement under all conditions is greater than 3 amps, it is
required to use this relay to activate the pump through an intermediate relay with a higher
power.
