Section N- Main Control Box Notes Primary Codes that pertain: 08, 09, 10, 11, 14, 15, 12, 13, 16, 17, 18 Additional Codes that pertain: 04, 19, 20, 22, 27, 32, 34, 35, 40 The Main Control Box is mounted in the Discharge Plenum Section (Section K) and is comprised of three primary parts— The Dead Door with the keypad, the Control Panel and the Power Panel. There have been four generations of Main Control Box used: 1. The original MicroTech Controls (Code 08= P/Code 12= 1M, 2M, 3M, 4M, 5M) which was used through 12/2000. This panel had a Main Processor (MCB) and a Keypad mounted on the Dead Door Assembly, an Output Board with a varying (depending on unit options) number of relays, and an ADI board mounted in the Control Panel. 2. The MicroTech II Control Panel (Code 08= P/Code 12= LD, LS, BD, BS, ED, ES, SD, SS) was used beginning in January, 2001. This MicroTech II box had the Main Processor (MCB) mounted in the Control Panel (the keypad still mounted in the Dead Door). NOTE: The power panel components for both of the above were the same. 3. The redesigned MicroTech II Control Box (Code 08= D/Code 12= LD, LS, BD, BS, ED, ES, SD, SS) was offered beginning in October of 2004, and was used exclusively after March, 2005. There is a MCB in the control panel. 4. The MicroTech III Control Box (Code 08= D/Code 12= LE, LF, BE, BF, EE, EF, SE, SF) was offered beginning in September of 2008. There is a MCB in the control panel. Units may also have no unit controls (Code 08= P or D/Code 12= YY, YM or YC) in which case the Main Control Box has no MCB but instead has a set of relays. Code 8 determines which generation of Control Box is installed- “P” is the original design (until 3/05); “D” is the current design (3/05 & later). Code 9 is the unit voltage and affects the transformer, and the fan overloads/MMPs, contactors, fuses, etc. Code 11 determines whether the main power connection is a terminal block or a through-the-door disconnect. Code 12 selects whether or not the unit has MicroTech controls or controls by others. Code 13 determines the presence of duct sensors, and the associated relays. Codes 14 and 15 determine the supply and return fans vanes and/or inverters. Code 17 determines whether there is a PVM, GFR and/or Line Reactors. Code 18 indicates whether a unit has a keypad display (remote or unit mounted) and if a modem is present (original MicroTech). Codes 19, 20 and 22 are return air codes, and impact several controls options. The presence of an OA hood, the horsepower of the return air motor, etc., have an impact on contactors, overloads, fuses, and duct sensors. Code 27 determines the draw through section, and can impact the cooling circuit relays. Code 32 determines horsepower for the supply fan motor which, like the return air motor will affect contactors, fuses, overloads, etc. Codes 04, 34, and 35 determine the blow-thru section, and the heat type, which will impact the transformers, heat circuit relays, and cooling circuit relays. Code 40 determines if there is a VAV damper. RoofPak Singlezone; RAH 077 “C” Rev. Q 07/12 RPL 700008300 / Page 164 ➩ ➩
