Part Part No. No. Other accessories may Changes section of this DESCRIPTION ANDUSAGE TheMotorMaster_ isafanspeed control device activated bya temperature sensor. It is specifically designed to control condenser fan motorspeedin response to the saturated condensing temperature during operation incooling mode only. For outdoortemperatures downto -20_'F.it maintains condensing temperature at100"F-+10°F. (See Fig.1.) Themounting control consists ofasolid-state circuit onaprinted circuit board inanaluminum extrusion, andasensor assembly to bemounted toareturn bend ontheunit'scondenser coil.A wire fromthesensor isconnected tothecircuitboard inthecontrol box. Parts necessary formounting control andsensor assembly are includedin the kit. Eitherassembly can be replaced independently oftheother. If anydamage totheprinted circuit boardor components is observed whenunpacking control assembly, return forreplacement. TheMotorMaster® maintains proper condensing temperature at anyambient temperature down to-20_'F. Nofieldadjustments or calibrations arerequired. Thefollowing must beobserved: • Ifspecial fanmotors orother accessories arerequired, install where necessary. • Measure unitpower supply voltage. Itmust meet minimum voltage specified onunitrating plate and match voltage rating ofMotorMaster®. • Make sure allunitsaremodified forwinter start control when needed. • Check thatcontrol location isasspecified. • Check thatsensor location isasspecified. • Make sure thatsensor wiring routing isasspecified. • Make sure windbaffles areinstalled onlyif required. • Forheat pump units, make sure isolation relay is available.

If motor runs when connected to single-phase voltage supply, but does not run when connected in series with MotorMaster®, check sensor as follows: a. Check temperature of return bend near sensor electronic thermometer. b. Disconnect both sensor with an leads. c. Check sensor resistance with an ohmmeter and compare resistance/temperature readings to those in Fig. 9. d. If sensor is within tolerance shown in Fig. 9, replace MotorMaster®.
