Ex. E <br />Programming Instructions (cont’d) <br /> 1 = Alarm outputs. Smoke alarm requires a manual reset. All other alarms are auto-reset. <br />2 = Alarms output. All alarms, including the smoke alarm, are auto-reset. <br />Setting 9: Anti Short Cycle time (1 through 10 minutes in 1 minute increments) Default = Off <br />Setting 10: Differential Between Stages (2°F through 12°F in 1° increments) Default = 2°F <br /> Differential Between Stages (1°C through 7°C in 1° increments) Default = 1°C <br />Setting 11: On-Off differential of Stage 1 (2°F through 5°F in 1° increments) Default = 3°F <br /> On-Off differential of Stage 1 (1°C through 3°C in 1° increments) Default = 2°C <br />Setting 12: On-Off differential of Stage 2 (2°F through 5°F in 1° increments) Default = 3°F <br /> On-Off differential of Stage 2 (1°C through 3°C in 1 degree increments) Default = 2°C <br />Setting 13: Blower Off Time Delay (0 through 90 seconds in 1 second increments) Default = 90 seconds <br />Pushing the Mode button, after programming Setting #13, or pushing and holding the Mode button for 4 seconds <br />while in the programming mode will return CommStat 3™ Controller to normal operation. <br />Alarm Relays and Smoke Alarm Input Connections and Reset Procedures <br />1. Alarm Relays to have a connection for the Common side of the relay switch. <br />2. Alarm Relays to have a connection for the Normally Open side of the relay switch that becomes Normally Closed <br />if the alarm detector is activated. <br />3. Alarm Relays to have a connection for the Normally Closed side of the relay switch that becomes Normally Open <br />if the alarm detector is activated. <br />4. When connecting a smoke alarm to the smoke alarm input terminals, remove the factory installed jumper wire <br />and install the smoke alarm leads. <br />5. Air Conditioner(s) locked out are reset as follows: <br /> The Lockout problem has been remedied on the unit(s) and if: <br /> • The high voltage power is turned off and then back on to the unit(s). <br /> • The 24 volt signal to the unit(s) is interrupted. <br /> • CommStat 3™ Controller is turned off and then back on. <br />6. Alarm Relays are reset as follows: <br />The Alarm problem has been remedied and if: <br /> • The high voltage power is turned off and then back on to the unit(s). <br /> • The 24 volt signal to the unit(s) is interrupted. <br /> • The Up and Down buttons on CommStat 3™ Controller are simultaneously pushed for 4 seconds. <br /> • CommStat 3™ Controller is turned off and then back on. <br />Operation Features <br />1. Program settings are retained during indefinite power loss. <br />2. Lag unit automatically becomes lead unit if lead unit losses power. <br />3. CommStat 3™ Controller will shutdown if the Smoke Detector is activated (has an open circuit). <br /> WARNING <br />® <br />All Marvair air conditioners (Models AVP) have an interlocking relay that turns on the indoor <br />blower whenever there is a call for heating. If the CommStat 3™ Controller is used on air <br />conditioners from other manufacturers, the indoor fan and electric heat must ALWAYS operate <br />simultaneously. The CommStat 3 Controller only turns on the electric heat. <br />4. Changeover differential between heating and cooling is a minimum of 4°F (2.2°C). <br />5. The power fail relay will be activated if 24 VAC power is not provided to the CommStat 3™ Controller. Since the <br />controller can be energized from either air conditioner, loss of input power from only one air conditioner will not <br />activate the power alarm relay. <br />3CommStat 3 PD, 8/10 Rev. 8 <br />
