System Controls and Wiring | Burnham 1100-H4 instruction

D.System Controls and Wiring

1.Refer to National Electric Code or Local Electric Codes for proper size and type of wire required. Follow Code.

2.Use anti-short bushings on all wiring passing through boiler jacket, junction boxes and/or control boxes.

3.Use armored cable (BX) over all exposed line voltage wiring.

4.If an Alliance™ indirect water heater is used, use priority zoning except for Hydro-Air Systems.

5.Single Zone Heating System – Refer to Figure 30 of this manual for the electrical diagram for this type of system. Set the thermostat heat anticipator to 0.60 amps.

6.Single Zone Heating System with Alliance™ Water Heater - Refer to Figure 31 of this manual for the electrical diagram for this type of system.

Set the thermostat heat anticipator to 0.60 amps.

7.Conventional Circulator Zoned System – Refer to Figure 32 of this manual for the electrical diagram for this type of system.

Read, understand and follow all of the instructions provided with the Honeywell R8888 control.

Connect the thermostat of each zone and the circulator for that zone to R8888 panel. If an Alliance™ indirect water heater is used, connect the Alliance™ thermostat and circulator to the Zone 1 terminals of the R8888.

Set the thermostat heat anticipator to 0.12 amps.

NOTICE

The Honeywell R8888 Control is available in a three (3) zone Model (R8888A) and a four (4) zone Model (R8888B). Up to four (4) R8888’s may be used together to provide control for up to twelve (12) individual zones. Only one (1) zone, the first zone of the main control, will provide priority circulation. If more than four (4) zones are required, connect additional R8888’s by wiring the A, B, and C terminals of each control together. Each R8888 requires a 120 volt power supply. If more than one (1) R8888 is used, set the panel type switch to “main” on the first R8888 and set the panel type switch to “expansion” on the second, third or fourth R8888.

8.Conventional Zone Valve Zoned System – Refer to Figure 33. Wiring to the most popular models of zone valves is given in Figure 34.

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.

NOTICE

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.
