The Energy Management Module(EMM) board is required for 4 to 20 mA, 2 or 3-step demandlimit control, chilled water temperature reset by space tempera-ture or 4 to 20 mA, and Ice Mode. Chilled water temperaturereset by return water or cooler delta T does not require the addi-tion of this accessory. See Table 1 for EMM functions. The fol-lowing functions are available with the EMM board:• Chilled Water Temperature Reset — Resets the chilledwater set point under less than full load capacity condi-tions by the following methods:— 4 to 20 mA Input: A field-supplied signal generatorand 1/2-watt, 250-ohm resistor are required.— Space Temperature: A field-supplied space tempera-ture sensor is required.• Demand Limit — Limits the capacity of the machine fromunit capacity by the following methods:— 4 to 20 mA Input: A field-supplied signal generatorand 1/ 2-watt, 250-ohm resistor are required.— 2 or 3-Step Switch Control: A field-supplied dry con-tact switch is required (One-Step Demand Limit doesnot require the EMM board).• Occupancy Override — Extends the occupied period formachine operation. A field-supplied dry contact switch isrequired.• Remote Chiller Lockout — Disables the chiller whenclosed. A field-supplied dry contact switch is required.• Ice Done Control Switch — Signals the machine to exitthe Ice Build mode and enter an unoccupied time period.A field-supplied dry contact switch is required.The following status functions are available with the EMMboard:• Capacity Output Signal — A 0 to10 vdc analog outputsignal indicating chiller capacity is available.• Shutdown Status Relay — A 24 vac output signal indi-cating that the machine is shutting down.• Alert Relay — A 24 vac output signal indicating the unithas an active alert.• Compressor Run Status — A 24 vac output signal (onefor compressor A, one for compressor B), indicating thecompressor is on.The EMM board can be configured with the Touch Pilotmodule.Table 1 — EMM Functions by UnitPackage Contents — Examine the package contentsfor correct part numbers. Refer to Table 2 for package con-tents and usage. If any of the components are damaged, filea claim with the shipping company and notify your Carrierrepresentative.WARNINGElectrical shock can cause personal injury and death. Shutoff all power to this equipment during installation. Theremay be more than one disconnect switch.
