Page 23: Main Set Point Temperature
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 13.5°F (-9.5°C) to a maximum setting of 105.0°... -
Page 24: Fan 1 Modulation Band
ECS 2M FAN 1 MOD. BAND The Fan 1 modulation band 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 modulation band 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°C). -
Page 25: Fan 1 Minimum Speed
CHAPTER 3 - USER’S GUIDE FAN 1 MIN 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 2M 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 percentage of time the fan is ON versus the percentage of time the fan is OFF. -
Page 27: Heater/Fan 2 Relative Set Point
CHAPTER 3 - USER’S GUIDE HEAT / FAN 2 REL. The Heater/Fan 2 relative set point is the relative temperature at which Heater/Fan 2 begins to operate. This value is the temperature difference from the main set point. When a heater is being controlled, the relative set point is below the main set point. - Page 28 ECS 2M REDUCT. PER DAY The reduction per day function automatically reduces the main set point by the set amount every 24 hours. The reduction setting is adjusted in 0.01 degree increments 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.
- Page 29 CHAPTER 3 - USER’S GUIDE LOW TEMP. 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 13.5°F (-10.0°C) to a maximum display of 105.0°F (40.5°C). If a temperature lower than 13.5°F is recorded, Lo is displayed.
- Page 30 ECS 2M HI TEMP. This function displays highest recorded temperature since the last clear. The record high temperature is rounded to the nearest 0.5 degree from a minimum display of 13.5°F (-10.0°C) to a maximum display of 105.0°F (40.5°C). If a temperature higher than 105.0°F is recorded, Hi is displayed.
- Page 31 CHAPTER 3 - USER’S GUIDE ROOM TEMP This function displays the room temperature. The Selector dial should normally be left at this position. The room temperature is displayed to the nearest 0.5 degree from a minimum display of 13.5°F (-10.0°C) to a maximum display of 105.0°F (41.0°C).

Page 32: Secondary Functions
ECS 2M SECONDARY FUNCTIONS REL. HUMIDITY SP If the ECS is equipped with an optional humidity sensor, this setting regulates the humidity level of the room. The humidity setting affects the operation of Fan 1 only. When the humidity level of the room exceeds the relative humidity setting, Fan 1 runs at a new minimum speed set by secondary function (3). - Page 33 CHAPTER 3 - USER’S GUIDE FAN 1 MOTOR The Fan 1 motor compatibility setting adjusts the ECS- 2M outputs to the electrical characteristics of the fan motor. Eight choices are available. Choice 1 is suited for most fans. If your motor is not listed in the compatibility table in the Appendix, try all choices and take the one that give the best performance with your fan.
- Page 34 ECS 2M FAN 1 MIN. HUM. This function establishes the minimum speed of Fan 1 when the relative humidity level of the room exceeds the relative humidity setting. The speed setting for humidity must be configured higher than the speed setting for temperature.
- Page 35 CHAPTER 3 - USER’S GUIDE FAN 1 PERIOD This function sets the maximum speed of Fan 1 when room temperature is higher the main set point. This value is entered as a percentage of maximum speed. Fan 1 maximum speed is adjusted in 2% increments from a minimum of 60% to a maximum of 100%.
- Page 36 ECS 2M HEAT/FAN 2 DIFF. In order to minimize erratic behavior of Heater/Fan 2 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. temperature difference between...
- Page 37 CHAPTER 3 - USER’S GUIDE MINIMUM RAMPING Minimum ramping is the lowest value that the ramping function can adjust the main set point to. This is a security feature. The minimum ramping setting 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°F (41.0°C).
- Page 38 ECS 2M LO TEMP. ALARM This function establishes the temperature difference below the main set point that the room can reach before a low temperature alarm is signalled. When a low temperature alarm occurs, an alarm contact is activated and the alarm LED lights up on the front panel.
- Page 39 CHAPTER 3 - USER’S GUIDE HI TEMP ALARM This function establishes the temperature difference above the main set point that the room can reach before a high temperature alarm is signalled. When a high temperature alarm occurs an alarm contact is acti- vated and the alarm LED lights up on the front panel.

Page 40: Relative Humidity Display
ECS 2M RELATIVE HUMIDITY 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 monitored, F2 is displayed. -
