Page 23: Main Set Point Temperature
CHAPTER 3 - USER GUIDE PRIMARY FUNCTIONS MAIN SET POINT The main set point establishes the target temperature in the building. This value is used as the reference point for other settings. The main set point temperature is adjusted in 0.5 degree increments from a minimum setting of 13.5°F (-9.5°C) to a maximum setting of 105.0°... -
Page 24: Fan 1 Differential
ECS 1M FAN 1 DIFFERENTIAL The Fan 1 differential setting establishes the temperature at which Fan 1 reaches maximum speed. The value is a temperature difference from the main set point. The Fan 1 differential is adjusted in 0.5 degree increments from a minimum setting of 2.0°F (1.0°C) to a maximum setting of 18.0°F (10.0°... -
Page 25: Fan 1 Minimum Speed
CHAPTER 3 - USER GUIDE FAN 1 MINIMUM SPEED This function sets the minimum speed of Fan 1 when room temperature is below the main set point. This value is entered as a percentage of fan maximum speed. The Fan 1 minimum speed is adjusted in 2% increments from a minimum setting of 12% to a maximum setting of 100%. -
Page 26: Fan 1 Duty Cycle
ECS 1M FAN 1 DUTY CYCLE As long as the actual temperature is below the main set point, Fan 1 operates at the minimum speed set by Fan 1 Minimum Speed (primary function 3). The Fan 1 duty cycle sets the per- centage of time the fan is ON versus the percentage of time the fan is OFF. -
Page 27: Ramping
CHAPTER 3 - USER GUIDE RAMPING The ramping function automatically reduces the main set point by the set amount every 24 hours. The ramping setting is adjusted in 0.01 degree decrements from a minimum setting of OFF, - 0.01°F (-0.01°C) to a maximum setting of - 0.99°F (-0.50°C) The main set point must be greater than the limit. -
