  2. Controller Layout

  3. Hardware Outlook

  4. 1. Features 2. Protections 3. Error Code 4. Operations Contents

  5. 1.1 System On/Off 1.2 Pump Control Function 1.3 Heat Rejection & Addition Output Stages 1.4 Outdoor Air Preset 1.5 Pre-cool / Pre-heat Protection Features

  6. Features 1.1 System On/Off • To Using remote On/Off switch (S1): • i) Standard Switch (without Smart Manager) • ii) Smart Manager • To start or stop the operation of the LWC. • The LWC shall function as: • i) System On if the remote On/Off switch (S1) is in closed circuit. • ii) System Off if the remote On/Off switch (S1) is in opened circuit.

  7. Features 1.2 Pump Control Function • Allows 2 loop circulating pumps with manual or auto lead lag control where operation is interchangeable. (a) Automatic 10sec 15sec Alarm • Lead pump on Water flow switch 10sec 15sec Alarm Lag pump on Water flow switch Off • Only one pump can operate. • If the water problem is verified and fixed, user can reset the remote • switch (S2) and the pump will resume operation. Alternatively it can • be reset by power supply. (b) Manual

  8. Features 1.3 Heat Rejection & Addition Output Stages • Total 12 sets of data output can be pre-set as heat addition or heat rejection stages. • The heat rejection and heat addition temperature setting shall be distributed in sequence and continuous (difference by 1ºC). 1.4 Outdoor Air Reset • The heat addition ON / OFF limit setting of the system is able to be increased in respond to a drop in the OD air temperature

  9. Features 1.5 Pre heat & Pre Cool Protection • To provide protection when the temperature exceeding the too high / low temperature (when system is OFF) Note: Pre-cool/heat temperature differential: 5ºC (fixed)

  10. 2.1 Low / Too Low Temperature 2.2 High / Too High Temperature 2.3 Loss of Flow 2.4 Sensor Error Protections

  11. System On No TW ≤ TLW ? Yes Sound Alarm System Continue Running No Yes System Off Sound Alarm TW ≤ TTLW ? Protections 2.1 Low / Too Low Temperature Note: TW = Water Temp TLW = Low Water Temp TTLW = Too Low Water Temp

  12. System On No TW ≥ TLW ? Yes Sound Alarm System Continue Running No Yes System Off Sound Alarm TW ≥ TTLW ? Protections 2.2 High / Too High Temperature Note: TW = Water Temp TLW = Low Water Temp TTLW = Too Low Water Temp

  13. 10s after System On Normal Check water flow for 15s Error Sound Alarm Lead Pump Off Lag Pump On Normal Error Check water flow for 15s System Off Sound Alarm Protections 2.3 Loss of Flow

  14. Protections 2.4 Sensor Error • If either the Water Supply sensor or OD Air sensor or both of • them gives an error signal during the system operates, the alarm • will activate 20 times per minute. • The unit will be Off. All heat rejection and heat addition stages • shall be shut down.
