HT# 059299-00 A Installation Mounting the Enclosure • Select a location near the equipment to be controlled. • The surface should be flat, sufficiently wide, and strong enough to hold the Multi-MOD. • Installation location should be away from extreme heat, cold, or humidity. • Remove the control from its enclosure by removing the top center screw and loosening ...

13 HT# 059299-00 A • The RS485 cable length must not exceed 3500 feet. • The RS485 cable must use one of the Platinum control’s enclosure side knockouts. Do not use bottom knockouts for communication cabling. • Connect the RS485 cable coming from the BACnet MSTP or Modbus network to the Black RS485 communication socket on the back of the control’s Communication ...

HT# 059299-00 A System Output Wiring (Terminals 3, 4) • The System output can be used to activate a pump, a pump starter, a combustion air damper, or other equipment. • The Multi-MOD Platinum activates the System output whenever there is a call for any of the stages. The System output remains energized whenever a stage is active. • The System output does not sour ...

15 HT# 059299-00 A 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 t ...
