CHAPTER 3 - USER’S 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 -9.5°C (13.5°F) to a maximum setting of 41.0°C (105.0°F).
ECS-3M 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°...
CHAPTER 3 - USER’S 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 a fan’s maximum speed. The Fan 1 minimum speed is adjusted in 2% increments from a minimum setting of 12% to a maximum setting of 100%.
ECS-3M 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.
CHAPTER 3 - USER’S GUIDE FAN 2 RELATIVE SET POINT The Fan 2 relative set point establishes the temperature above the main set point at which Fan 2 begins to operate at its minimum speed. The value is a temperature difference from the main set point.
ECS-3M FAN 2 DIFFERENTIAL differential setting temperature at which Fan 2 reaches maximum speed. The value entered is the temperature difference above the Fan 2 relative set point temperature setting. The Fan 2 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°...
CHAPTER 3 - USER’S GUIDE FAN 2 MINIMUM SPEED When room temperature is at the Fan 2 relative set point, Fan 2 runs at minimum speed set by this function. This value is entered as a percentage of fan maximum speed.
ECS-3M HEATER/FAN 3 RELATIVE SET POINT The Heater/Fan 3 relative set point is the relative temperature at which Heater/Fan 3 begins to operate. This value is the temperature difference from the main set point. When a heater is connected,the relative set point is below the main set point.
CHAPTER 3 - USER’S GUIDE REDUCTION PER DAY The reduction per day (ramping) function automatically reduces the main set point by the set value every 24 hours. The reduction setting is adjusted in 0.01 degree decrements from a minimum setting of OFF, -0.01°C (-0.01°F) to a maximum setting of -0.50°C (-0.99°F).
ECS-3M RECORD LOW TEMPERATURE This function displays the lowest recorded temperature since the last clear. The record low temperature is rounded to the nearest 0.5 degree from a minimum display of -10.0°C (13.5°F) to a maximum display of 40.5°C (105.0°F). If a temperature lower than -10°C is recorded, Lo is displayed.
CHAPTER 3 - USER’S GUIDE RECORD HIGH TEMPERATURE This function displays the highest recorded temperature since the last clear. The record high temperature is rounded up to the nearest 0.5 degree from a minimum display of -10.0°C (13.5°F) to a maximum display of 40.5°C (105.0°F).
ECS-3M ROOM TEMPERATURE This function displays room temperature. The Selector dial should normally be left in this position. Room temperature is displayed to the nearest 0.5 degree from a minimum display of -10.0°C (13.5°F) to a maximum display of 41.0°C (105.0°F). If the temperature is lower than -10.0°C, Lo is displayed.
CHAPTER 3 - USER’S GUIDE SECONDARY FUNCTIONS RELATIVE HUMIDITY SET POINT This setting regulates room humidity only when a humidity sensor is connected to the ECS. The humidity setting affects Fan 1 only. When humidity in the room exceeds the relative humidity set point, Fan 1 minimum speed increases gradually and proportionally.
ECS-3M FAN 1 MOTOR The Fan 1 motor compatibility setting adjusts ECS-3M outputs electrical characteristics of the fan motor. Eight choices are available. Choice 1 is suitable for most fans. If your motor is not listed in the compatibility table in the Appendix, try all choices and take the one that offers the best performance.
CHAPTER 3 - USER’S GUIDE FAN 1 MINIMUM SPEED FOR HUMIDITY This function establishes the minimum speed of Fan 1 when the relative humidity level of the room exceeds the relative humidity set point. The speed setting for humidity must be set higher than the speed setting for temperature.
ECS-3M FAN 1 DUTY CYCLE PERIOD The Fan 1 duty cycle period is adjusted in conjunction with the Fan 1 duty cycle timer (primary function 4). The Fan 1 duty cycle period is the total time in ON-OFF fan cycle. The period is adjusted in 1 minute increments from a setting of 1 minute to a maximum setting of 10 minutes.
CHAPTER 3 - USER’S GUIDE FAN 2 MOTOR The Fan 2 motor compatibility setting adjusts the ECS-3M outputs to the electrical characteristics of the fan motor. Eight choices are available. Choice 1 is suitable for most fans. If your fan is not listed in the compatibility table in the Appendix, try all choices and take the one that gives the best performance.
ECS-3M HEATER/FAN 3 DIFFERENTIAL In order to minimize erratic behavior of Heater/Fan 3 when room temperature is exactly at the relative set point, the differential setting separates this ON/OFF threshold into two: one ON threshold and one OFF. This feature greatly reduces equipment wear.
CHAPTER 3 - USER’S GUIDE MINIMUM RAMPING Minimum ramping is the lowest that the ramping function can adjust the main set point to. This is a safety feature. The minimum ramping setting is adjusted in 0.5 degree increments from a minimum setting of -9.5°C (13.5°F) to a maximum setting of 41.0°C (105.0°F).
ECS-3M LOW TEMPERATURE ALARM This function establishes the temperature difference below the main set point that the room can reach before a low temperature alarm is sounded. When a low temperature alarm occurs, an alarm contact is activated and the alarm LED lights on the front panel.
CHAPTER 3 - USER’S GUIDE HIGH TEMPERATURE ALARM This function establishes the temperature difference above the main set point that the room can reach before a high temperature alarm is sounded. When a high temperature alarm occurs, an alarm contact is activated and the alarm LED lights on the front panel.
ECS-3M RELATIVE HUMIDITY DISPLAY This function displays the relative humidity of the room. Relative humidity is displayed in 1% increments from a minimum display of 30% to a maximum display of 90%. If a humidity level lower than 30% is sensed, F2 is displayed.
