BP-VALVE (By-pass Valve): Enabled/Disabled, For more information, see page 22.
By-pass Valve Description
The purpose of the automatic BPVALVE (bypass valve) feature is to by-pass the ow of water from the heater inlet to the
heater outlet when the heater is not ring. There is a minimal amount of water ow through the heater when the heater
is not ring, and a maximum water ow through the heater when the heater is ring. For more information about Manual
By-Pass and Automatic By-Pass valves, see page 22.
By-Pass Enabled
When the BYPASS VALVE feature is enabled and there is a call for heat, the by-pass valve closes to allow
water to ow through the heater. It takes 30 seconds for the bypass valve to rotate to the closed position. This allows
the valve to complete rotation so there is sufcient water ow and pressure to prevent the water pressure switch from
trigging an error. When the call for heat ends, the water ow continues through the heat exchanger for a cool down
period of one minute. After the cool down period, the by-pass valve will rotate so that water no longer ows through
the heater.
By-Pass Disabled
When the BYPASS VALVE feature is disabled, there is no automatic switching of the by-pass valve when the heater
starts a heating cycle. The valve stays in the position and water always ows through the heater.
