Conventional Zone Valve Zoned System - Burnham Revolution Installation, Operating And Service Instructions

8. Conventional Zone Valve Zoned System – Refer to Figure 36. If a system water temperature limit is used, refer to Figure
37. Wiring to the most popular models of zone valves is given in Figure 38.
Locate the group of two (2) wires (yellow and white) in the junction box at the inside top of the boiler jacket. Connect
wires from these boiler wire leads to the system circulator wire leads.
Locate the group of two (2) thermostat wires (black and black) inside the boiler jacket at the top (not inside the boiler
junction box. Connect wires from these boiler wire leads to the H1 and H2 of the R8889 control.
If a system water temperature limit (L4006 Aquastat) is used do not install in the H1 or H2 circuit. An additional
Honeywell R8225 relay is required. Refer to Figure 37 for this type of system.
Connect the thermostat of each zone and the zone valve for that zone to the R8889 control. If an Alliance™ indirect water
heater is used, connect the Alliance™ thermostat and zone valve to the "zone 1" terminals of the R8889.
Set the thermostat heat anticipator to 0.12 amps.
The Honeywell R8889 Control is available in two three (3) zone models and two four (4) zone models.
Burnham recommends using Model R8889A for three (3) zone systems and Model R8889B for four (4) zone
systems. Models R8889C and R8889D have less load capacity and may not operate with certain types of
zone valves. Up to four (4) R8889's may be used together to provide up to sixteen (16) individual zones.
Only one (1) zone, the first zone of the main control will provide priority zoning for the Alliance indirect
water heater. If more than four (4) zones are required, connect additional R8889's by wiring the A, B and
C terminals of each control together. Each R8889 requires a 120 volt power supply. If more than one (1)
R8889 is used, set the panel type switch to "main" on the first R8889 and set the panel type switch to
"expansion" on the second, third or fourth R8889.
9. Burnham EC5000 Circulator Zoned System – Refer to Figure 39 of this manual for the electrical diagram for this type of
system. Wire the system as indicated in that diagram. Refer to the manual provided with the Burnham EC5000 Control
for control operation and setup details.
10. Burnham EC5000 Zone Valve Zoned System – Refer to Figure 40 of this manual for the electrical diagram for this type
of system. Wire the system as indicated in that diagram. Refer to the manual provided with the Burnham EC5000 for
control operation and setup details.
11. Radiant Floor Circulator Zoned System with Alliance™ Water Heater - Refer to Figure 41 of this manual for the
electrical diagram for this type of system. Wire the system as indicated in that diagram.
Refer to Burnham Radiant Heating Manual for additional information.
12. Radiant Floor Zone Valve Zone System with Alliance™ Water Heater - Refer to Figure 42 of this manual for the
electrical diagram for this type of system. Wire the system as indicated in that diagram.
The Burnham EC5000 Control includes a water temperature sensor. Mount this sensor to the system
supply piping. Do not mount this sensor on the boiler supply pipe.
An additional water temperature limit (L4006 Aquastat) is not needed with Burnham EC5000 Control since
the control already has a system temperature sensor.
