OPERATION WITHOUT the ENERGY MANAGER
SERVICE BOARD MODE:
The Display Manager can be placed into “E100 (SERVICE BOARD)/E150 (CLASSIC MANAGER 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 is similar to inserting the traditional green “Service Board”. The
traditional service board may still be used if desired. E100 (SERVICE BOARD) allows the boiler to run like a conventional
boiler for the first ten minutes. After which, it will switch to the E150 (CLASSIC MANAGER MODE). In CLASSIC
MANAGER MODE, instead of maintaining temperature, the system will operate as the original “Classic” manager did.
The burner will only run during a call for heat and will post purge to the last zone(s) calling based on time instead of
temperature and time.
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
o
/180
o
F.
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
o
/180
o
F and zone will get heat on call.
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.
EMERGENCY HEAT WITHOUT ENERGY MANAGER or RELAY BOARD
(Temporary Operation Only – 5 minute wiring change)
Method A (Heat and Hot Water):
If the relay board is functioning properly, install a service board or follow the wiring
instructions in the Owner and Installation Manual to run without a manager.
Method B (Heat Only) – Temporarily relocate (3) wires shown by arrows:
1) Move the black 120VAC wire from PWR to BURN (shown below).
This will apply power continuously to the main circulator which will circulate water throughout all of the open heating
zone valves. The stairway switch may be used to stop the circulator (and inducer if sidewall vented) if desired.
2) Select one thermostat that will control when the boiler runs to add heat to the house. Move that representative
thermostat (T1, T2, T3, or T4) from the left side of the manager to B1. Move the other wire from that thermostat from
A1 to B2. B1 and B2 connect internally to TT on the burner.
3) Turn down the high limit aquastat to 165°F/180°F and test and confirm proper and safe function. *When returning to
service, reset high limit to 205°F/215°F.
4) Manually open all desired zone valves and close return valve a bit.
There will not be any condensing protection without the manager; closing the return a bit will help limit condensing of flue
gases.
NOTE for sidewall vent systems: Add a 120VAC jumper from BURN to IND. This will run the inducer continuously, so
caution should be used in systems without antifreeze.
