Page 3: Introduction
Aegis Sequencer INTRODUCTION 1. INTRODUCTION The Aegis Sequencer controller can be used in all systems where several Aegis heat pumps are installed parallel to each other, using the same water tank system, and requiring a common control point. The system can include up to six units, and can manage a secondary side water pump. The device can detect the thermal demand of the tanks and activate the appropriate number of units. -
Page 4: Ethernet Network
Aegis Sequencer System Composition 2.2. Ethernet Network The Aegis units (slaves) connect to the Aegis Sequencer cascade controller (master), via an Ethernet network with a star structure. Modbus TCP communication protocol is used between the master and the slaves. The network switch is pre-installed inside the electrical panel. By connecting the switch to the local network, the end user can access the unit's web server from a local network, or read the system’s information via BMS. -
Page 5: Setup
Aegis Sequencer Setup 3. Setup 1. Provide 120V power to the unit at the main switch on the top-right of the cabinet. Electrical protection and a disconnect switch must be field-provided by a licensed electrician as per local code requirements. 2. - Page 6 Aegis Sequencer Setup III. Go to d. Network Configuration tab and press enter. Input the following settings: • Enable: Static • Set IP address to 192.168.1.152 • MASK: 255.255.255.000 • GW: 192.168.1.1 • DNS: 192.168.1.1 6. Search and record the IP address of each Aegis A heat pump being connected to the sequencer. Set the Slave parameters to match the IP address of each unit in order.
- Page 7 Aegis Sequencer Setup Ensure the Slave ID # is matches the number of the unit (example: Unit 3 has Slave ID 3). Repeat these steps until all units have their matching IP addresses in the Slave Parameters. 7. Disable Temperature Probes BT1 and BT2 for each unit. These settings are accessed through the remote interface of each unit.
