STAGe OuTPuT AND BOIleR PuMP WIRING
• To have the Multi-MOD Platinum operate the boilers and their pumps, use
SPDT relays (Single-Pole Double-Throw) and TDR relays (Time-Delay
relay) .
• The SPDT relay sends the activation signal from the Multi-MOD Platinum
stage activation output to the boiler Interlock (TT) and its pump .
• The TDR relay receives the SPDT pump activation signal and send it to the
pump . When the SPDT relay signal ends, the TDR keeps the pump running
for an additional period . This additional delay acts as the Run-On delay
available for the System output . See "System Run-On" on page 34 .
135Ω MODulATING MOTOR WIRING
Stage1 (Terminals C1, C2, C3), Stage2 (Terminals C4, C5, C6),
Stage3 (Terminals C7, C8, C9), Stage4 (Terminals C10, C11, C12)
• The Multi-MOD Platinum can operate up to four 135 Ω modulating motors
(Multi-MOD ordered with 135-Ohm Output cards .) Each 135 Ohm Output
card operates two stages . See "Modulating Output Card Installation" on
page 23 .
• Terminals C1, C4, C7, and C10 on the Multi-MOD Platinum connects to the
modulation decreasing terminals on the burners (Blue/Black modulating
wires) .
• Terminals C3, C6, C9, and C12 on the Multi-MOD Platinum connects to the
modulation increasing on the burners (White modulating wires) .
• Terminals C2, C5, C8, and C11 on the Multi-MOD Platinum connects to the
modulation common terminals on the burners (Red modulating wires) .
WIRING TO 4-20 MA MODulATING MOTORS
Stage1 (Terminals C1, C2), Stage2 (Terminals C4, C5),
Stage3 (Terminals C7, C8), Stage4 (Terminals C10, C11)
• The Multi-MOD Platinum can operate up to four 4-20 mA modulating
motors (Multi-MOD ordered with C/V (Current/Voltage) output cards) . See
"Modulating Output Card Installation" on page 23 .
• To program the control for 4-20 mA output, See "Output Type" on page 27 .
• Apply the supplied label marked Current/Voltage below the modulating
terminals .
• The Multi-MOD sources 24VDC excitation voltage for the 4-20mA signal .
