2.10 DOMESTIC HOT WATER (DHW) PRIORITY Domestic hot water priority is accomplished by providing a contact closure to the ECCS panel from a domestic hot water tank. The ECCS panel sends out 24V on terminal L+ and receives voltage back on terminal I0:0 when DHW priority is called for. When I0:0 receives a signal the following sequence occurs: 1.) The control compares the DHW setpoint (which is set on the System Setup Screen, See Figure: 5.3.) to the system generated by Outdoor reset curve or fixed setpoint. If the DHW setpoint is higher, the DHW setpoint will become the new setpoint. If the DHW setpoint is lower than the existing setpoint it will not change the setpoint. 2.) If the system is in the WWSD mode, the system will be taken out of the WWSD mode and start boilers until the system water temperature is brought up to the DHW setpoint. NOTICE The ECCS System WILL NOT start any pumps or open valves in the DHW piping. This must be provided by others. 2.11 ALARMS a. The ECCs will annunciate and record alarms on the screen that come from the individual boilers. Any of the faults from the flamesafeguard are annunciated through Modbus communication to the ECCS panel. The format for the alarms can be viewed in Fig 5.9. The alarm will indicate which boiler is in alarm, the fault code #, and a description of the 7 most common faults. This includes Main Flame Failure, Main Flame Ignition Failure, Pilot flame failure, Air flow failure, lockout interlock, Running interlock and Flame detected. If it is one of the other 100+ possible alarms it will just display the fault code for the Flame safeguard. In addition there are alarms for High water temperature(above 230F), Low water temperature (below 120F), and communication failure. A communication failure occurs when the communication over the Modbus is interrupted by either losing power to the boiler or there is a break in the wiring. b. The ECCS stores 100+ alarms in the history screen. Every alarm is time and date stamped when it Occurs, when it was Acknowledged, and when it was Cleared. See Fig 5.8. The screen does not have any permanent memory so if the power is turned off to the panel the alarm history is lost. c. As long as an alarm is active, there will be a small box with an exclamation point in it at the bottom of the screen. This will also have the # of active alarms at the bottom of the box. d. External alarm indication – A 24vdc relay(supplied by others) can be power by the ECCS between terminals O:0.7 and M for an alarm indication. Refer to Fig 3.4. 2.12 EXTERNAL ENABLE/DISABLE See 2.6 Warm Weather Shut Down on page 7. 8
Section 3: Installation 3.1 UNPACKING 3.1.1. Inspection CAUTION Do not lay panel down on touch screen. Panel weighs approximately 25 lbs. Use proper lifting techniques when handling. a. Inspect the shipment carefully for any signs of damage. All equipment is carefully manufactured, inspected and packed before shipment. Our responsibility ceases upon delivery of the ECCS panel to the carrier in good condition. The consignee must file any claims for damage or shortage in shipment immediately against the carrier. Thermal Solutions Products, LLC will allow noclaims for variances or shortages unless presented within thirty (30) days after receipt of equipment. b. The ECCS system will include: (1) Panel with touch screen mounted in front door. PLC inside with terminal strips and breaker. (1) System water temperature sensor and thermowell. (1) Outdoor air temperature sensor. WARNING Carefully read all instructions before installing panel. Failure to follow all instructions in proper order can cause personal injury or death. 3.2 MOUNTING 3.2.1. Panel a. The ECCS system must be installed to conform with the requirements of the local and state authority having jurisdiction, or in the absence of such requirements, to the latest release of the National Electric Code, ANSI/NFPA 70. b. Provide clearance around panel for wiring conduit and access to panel. Allow 26" in front of panel to allow door to be opened and personnel access to touch screen. Allow 4” on bottom, top and sides to allow clearance for conduit. c. Mount in the vertical position. Door hinges on left side with touch screen facing out. See Figure 3.1 for physical size and details on mounting holes. d. Panel is rated for NEMA 12 service. When attaching conduit, enter from bottom of panel to prevent water from gravitating down the conduit into the box. 3.2.2. System Water Temperature Sensor a. Mount the thermowell and sensor in a 3/4" coupling in the common header downstream of all boiler connections. Maintain a minimum distance of 10 pipe diameters for connections. See Figure 3.3 System Wiring. 3.2.3. Outdoor Air Temperature Sensor a. Mount the temperature sensor on an outside wall out of direct sunlight, preferably a north facing wall. b. Do not mount sensor near exhausts of any kind, this may affect readings. WARNING Installation of this panel should be undertaken only by trained and skilled personnel from a qualified service agency. 9
