Temperature Limit Switch (TLS) - This control islocated inside the heater compartment and is set toopen at the temperature indicated in the ElectricHeat Limit Control Setting Table 29. It resets auto-matically. The limit switch operates when a hightemperature condition, caused by inadequate sup-ply air flow occurs, thus shutting down the heaterand energizing the blower.HEAT ANTICIPATOR SETPOINTSIt is important that the anticipator setpoint be correct.Too high of a setting will result in longer heat cyclesand a greater temperature swing in the conditionedspace. Reducing the value below the correct setpointwill give shorter “ON” cycles and may result in the low-ering of the temperature within the conditioned space.Refer to 30 for the required electric heat anticipator set-ting.TABLE 29: ELECTRIC HEAT LIMIT CONTROLSETTINGVOLTAGE kW TEMPERATURE LIMIT SWITCH Open Temp ºF5 1 1407 1,3 14010 1,2,3 14015 2,4,6 1401,2,3,4,5 1406 15030 1,2,3,4,5,6 1505 1,2,3 1407 1,2,3 14010 1,2,3 15015 2,4,6 14020 1,2,3,4,5,6 1501,3,5 1602,4,6 1507 2,4,6 14010 2,4,6 14015 2,4,6 14020 3 16030 3 15010 2,4,6 14015 2,4,6 14020 5 16030 5 1502030230-3-60460-3-60575-3-60230-1-60TABLE 30: ELECTRIC HEAT ANTICIPATORSETPOINTSHEATERKW VOLTAGE SETTING, AMPSTH1 TH25230-1-60230-3-600.024 0.357 0.024 0.3510 0.024 0.3515 0.024 0.3520 0.024 0.3530 0.024 0.357460-3-600.024 0.3510 0.024 0.3515 0.024 0.3520 0.024 0.3730 0.024 0.3710575-3-600.024 0.3515 0.024 0.3520 0.024 0.3730 0.024 0.37
