Hot Water Priority
For a typical oil fired boiler with a sound chimney, supplying domestic hot water and properly sized heat zones, all
option switch settings will be "OFF". Turn switch 1 on to provide increased condensing protection (recommended for gas
fired boilers). Switches 5 through 8 are usually off, but can be turned on if the heat zone tends to overheat during energy
recovery. Switch 9 is usually off, but can be turned on to supply higher temperature water to under-radiated heating
zones or during very cold weather. Switch 10 is usually off, but when turned on the Manager will close heat zones 1
through 4 during a hot water call for up to 25 minutes.
SECURITY SYSTEM INTERFACE WIRING
The System Manager features a monitor interface system, which allows the Manager to alert a security system or
other signal light or device when a problem is detected. A three-terminal connector is supplied with each Manager. The
wiring detail is shown in figure below. NOTICE: Some security systems may require an "abort delay" of one second to
avoid a transient signal on Manager power-up. If an abort delay is not available, use Energy Kinetics System Monitor
(provided separately part # 10-0168). Alarm contacts are "dry" (no voltage is provided).
