OPERATION WITHOUT the DIGITAL MANAGER
The Digital Manager can be placed into "SERVICE BOARD MODE" by turning off the system switch and
removing the RED temperature sensor lead from the left side input connector, and turning power back on. Removing the
RED lead does exactly the same thing as inserting the traditional green "Service Board". The traditional service board
may still be used if desired. SERVICE BOARD MODE allows the boiler to run like a conventional boiler. The burner is
controlled by the high limit aquastat and the circulator runs continuously. If this mode is used, temporarily reset high limit

o
aquastat to 165
/180
F.
TEMPORARY OPERATION WITH JUMPERS
(With partially functional Manager still in place and without service board)
If a particular function of the Manager fails, use appropriate jumper action below with Manager in place.
BURNER: Jumper BB or TT on burner control. Burner will run on limit whenever Manager calls circulator. The boiler
may overheat slightly during energy recovery. Temporarily reset limit aquastat to 165
MAIN CIRCULATOR: Remove blue CIRC lead from right side and connect to A2 on the left side, using an extension
lead. The circulator will run constantly and the burner runs on Manager call.
ZONE/HOT WATER CONTROL: Remove zone valve and thermostat leads for zone. Connect a thermostat lead to
A1. Connect a zone valve lead to A2. Wire the remaining thermostat and zone valve leads together. Zone valves will
open whenever the Thermostat calls but it will not activate manager. If system is active, zone will receive heat when
another calls or run system with high limit aquastat set to 165
IF A PLUG-IN RELAY FAILS: Replace with spare relay. If spare is not available, temporarily install a relay with
24VAC coil and 120VAC contacts. Contact Energy Kinetics for connection details.
