COMMERCIAL STEAM GENERATOR EXECUTIVE SERIES (ES) WITH AUTO POWER FLUSH


INTRODUCTION TO PROGRAMMING

The steam generator operates based on the thermostat and the 24h/7day timer setting. The thermostat controls and maintains the desired temperature in the steam room (which can be set by user) and the timer controls the daily operation schedule for the unit (e.g. start time and shut down time). Users according to their desired application can set these controls. The thermostat and timer programming instructions is explained below.

THERMOSTAT FUNCTIONS AND SET UP

The A419 Control Functions

Setpoint (SP) establishes the temperature value at which the equipment is switched on or off. Setpoint range is –30 to 212°F or –34 to 100°C (in 1-degree increments).

Differential (DIF) establishes the difference in temperature between the ON and OFF cycle. For example if the SP=117 and the DIF=3 unit goes OFF at 117°F and comes back ON at 113 which is (117-3-1=113). The differential is set relative to Setpoint and may be set from 1 to 30 °F or °C (in 1-degree increments).

Anti-Short Cycle Delay (ASD) establishes the minimum time that the unit stays in OFF cycle before the next ON-cycle. The ASD does not allow the unit to re-energize until the programmed time delay has elapsed. The delay is activated when the control is first turned on and every time an on-cycle ends. When the delay is activated, the LCD alternately flashes the sensor current temperature and ASD. The antishort Cycle Delay range is 0 to 12 minutes (in 1-minute increments).

Sensor Failure Operation (SF) establishes how the A419 control’s output-relay operates the equipment in the event of a sensor or sensor wiring failure. The user may select to keep the unit running or to shut it down after the sensor failed. When the control detects a sensor circuit failure, the LCD flashes SF alternately with OP (if the sensor circuit is open), or SH (if the sensor circuit is shorted). Before indicating a failure, the control implements a 1-minute delay, which allows verification of failure condition and avoids nuisance failure indications.

Temperature Offset (OFS) establishes a secondary Setpoint value that may be invoked to control the temperature in the room when a 30- minute timer or in-room-touch timer is activated in the steam room (and BIN appears on the display). Offset range is 0 to 50 °F or °C (in 1-degree increments). For example if the OFS=25F and the SP=117F, with the timer in OFF position, the unit operates at normal setpoint which is 117; but with the timer activated the unit operates at 92F which is (117-25) and the display shows a BIN sign as long as the timer stays activated.


Changing the A419 Control Temperature Units

IMPORTANT: Make sure the Touchpad Lock Jumper is installed (unlocked) before attempting to adjust the A419 control functions. See Figure 5.

The A419 control is factory set to display Fahrenheit or Celsius according to the region standards. To change to Celsius, press Up and Down (arrows) simultaneously. Press them again to display Fahrenheit units. Verify that the control is displaying the desired temperature units before setting the Setpoint.

Setting the A419 Control Setpoint Value

To view and adjust Setpoint, follow these steps:
1. Press and hold MENU (about 2 seconds) until the display flashes SP.
2. Press MENU again to display the existing setpoint value.
3. Press Up or Down (arrows) to change the setpoint value.
4. Press MENU again to save the new value. The display returns to the current sensor temperature.
Note: If no setup entry is made for 30 seconds, the control reverts to the (normal) temperature display.

IMPORTANT: If MENU is not pressed after changing the setpoint value, the control reverts to the previously programmed setpoint value.




Setting the other A419 Control Functions
To set the Differential, Anti-short Cycle Delay, Temperature Offset, or Sensor Failure operation, use the following method.
1. Press and hold MENU until the display changes to flashing SP. (This takes about 2 seconds.)
2. Press Up or Down (arrows) repeatedly until the desired function is displayed. (See Table 3.)
3. Press MENU to display the function’s current value.
4. Press Up or Down (arrows) until the desired value is reached.
5. Press MENU to save the new value. The display returns to the current sensor temperature.

IMPORTANT: If MENU is not pressed after changing the settings, the new settings are not saved and the control reverts to the previously programmed setting values.

Notes:
  • If no setup entry is made for 30 seconds, the control reverts to the (normal) temperature display.
  • Any saved A419 control setting is non-volatile and remains in the control’s memory during power
    interruptions.
  • The sum of the Setpoint and Differential values must be within the Setpoint range, or the control may not
    function properly.
IMPORTANT: Do not set Setpoint and Differential values which (when totaled) fall out of A419 control’s Setpoint range (-30 to 212°F [-34 to 100°C]). The control will not function properly if these values are outside of the control’s Setpoint range.

PROGRAMMING DAILY SCHEDULE FOR THE UNIT

EC7000 TIMER

INTRODUCTION
The EC7000 is a single-channel, electronic timer that controls the unit with a time-of-day schedule. The control may be utilized as a 24-hour or 7-day control. As a 24-hour control the same ON/OFF program is utilized each day of the week. Saturday and/or Sunday, or any other day may be skipped. When schedules vary from day to day, the 7-day programming capability allows a different schedule for each day of the week. With 16 setpoints available, these time controls provide programming versatility.

SPECIFICATIONS – PROGRAMMING CAPABILITIES
16 Setpoints – A setpoint defines the type of event (ON or OFF) as well as the time and day(s) on which the event will occur.
24-Hour or 7-Day programming – Allows the same schedule or a different schedule for each day of the week.
Selectable Clock Format – 12-hour (AM/PM) or 24-hour format.
Manual Override – Reverses current output state; begins immediately when initiated and remains until overridden again or until next setpoint is reached.

POWER OUTAGE CARRY-OVER
The program and time-of-day are maintained during a power outage for a minimum of seven (7) days. A built-in special capacitor eliminates the inconvenience of battery replacement.

ENVIRONMENTAL
EC7000 should be mounted indoors in an environment that is free from excessive contaminants such as oil, moisture and dirt. EC7000 is suitable for both indoor and outdoor use.




Before you begin programming, make sure you understand setpoints. A setpoint defines the type of event – ON or OFF – as well as the time of the event and the day(s) on which the event will occur. For example, to turn the unit ON at 5:00 AM each day of the week, a setpoint like this would be required: ON, 5:00 AM, Mon-Tue-Wed-Thur-Fri-Sat-Sun. Setpoint programming provides built-in skip-a-day capability; to skip any day(s), simply do not add the day(s) to the setpoint. You must set the timer as it shuts down the boiling cycle for at least 1 hour in any 24 hours period.

As a simple example, consider the following schedule for turning the unit ON and OFF:
   SUN: Unit is OFF.
   MON through FRI: Unit is ON at 7:30 AM, OFF at 5:30 PM
   SAT: ON at 7:30 AM, OFF at 12:30 PM

Note:
When programming, “NO” on the display means no event is required at that setpoint on that particular day. “YES” means an event is required (either On or OFF) at that setpoint on that day. The sample schedule would be arranged as follows:
     1st setpoint: SUN: NO, MON through SAT: YES; ON; at 7:30 AM
     2nd setpoint: SUN: NO,MON through FRI: YES, SAT: NO; OFF; at 5:30 PM
     3rd setpoint: SUN through FRI: NO, SAT: YES; OFF; at 12:30 PM

Mark your setpoint work sheet as following table and proceed to grogram the unit using the programming instruction.

11. RUN Return to the RUN mode when programming is complete.


NOTE: Once programming has been completed through step 11, the display should show correct Time-of-Day, Day-of-Week and Setpoint status (ON/OFF). If present load status should be an ON event, but shows as an OFF event, press ENTER/OVR to turn load ON and to initiate programmed schedule.

TO REVIEW SETPOINTS
STEP KEY DESCRIPTION
1. MODE Advances from RUN mode to SET TIME mode (TOD displays)
2. MODE Advances from SET TIME mode to SETPOINT PROGRAMMING mode. The control will display the first setpoint ( 1 displays at bottom). To modify the setpoint, go to step 2 of the SETPOINT PROGRAMMING mode instructions.
3. > Advances through the remaining setpoints.
4. RUN Returns to RUN mode when done reviewing setpoints.


OVERRIDE
Manual override reverses the current output state. Loads that are ON turn immediately OFF; loads that are OFF turn immediately ON. The timer displays OVR to indicate that the current load state is the result of an override. The override remains in effect until overridden again or until the next setpoint is reached. To initiate override, press OVR (ENTER) key while in the RUN mode.

NOTE: After an override has been initiated, the OVR will display until the next programmed setpoint is reached, even if the timer is overridden again. Display will show if the load is on or off.
