Page 3: General Recommendations
General Recommendations As you review this manual, keep in mind that: • All fi eld-installed wiring must conform to European guidelines and any applicable local codes. Be sure to satisfy proper equipment grounding requirements per European guidelines. • Compressor motor and unit electrical data (including motor kW, voltage utilization range, rated load amps) is listed on the chiller nameplate. - Page 4 General Recommendations WARNING! Hazardous Voltage - Pressurized Burning Fluid: Before removing compressor terminal box cover for servicing, or servicing power side of control panel, CLOSE COMPRESSOR DISCHARGE SERVICE VALVE and disconnect all electric power including remote disconnects. Discharge all motor start/run capacitors. Follow lockout/tagout procedures to ensure the power cannot be inadvertently energized.

Page 5: Installer-Supplied Components / Interconnecting Wiring
Installer-Supplied Components / Interconnecting Wiring Installer-Supplied Components Customer wiring interface connections are shown in the electrical schematics and connection diagrams that are shipped with the unit. The installer must provide the following components if not ordered with the unit: • Power supply wiring (in conduit) for all fi eld-wired connections. •... - Page 6 Installer-Supplied Components / Interconnecting Wiring Water fl ow proving When unit controller water fl ow proving is confi gured for a Paddle water Flow switch, it will require a high voltage binary input (110V-220V). When confi gured for a Thermal dispersion water fl ow switch, it requires a binary low voltage input (12-24V).

Page 7: Programmable Relays
Programmable Relays 4 programmable relays are provided for enunciation of certain events or states of the chiller, selected from a list of likely needs, while only using four physical output relays, as shown in the fi eld wiring diagram. The relays contacts are isolated Form C (SPDT), suitable for use with 120 VAC circuits drawing up to 2.8 amps inductive, 7.2 amps resistive, or 1/3 HP and for 240 VAC circuits drawing up to 0.5 amp resistive. - Page 8 Programmable Relays The output is true whenever the chiller has reached maximum capacity continuously for the Max Capacity Maximum Capacity Relay debounce time for either cooling or heating. The output is false when the chiller does not have all its available compressors running continuously for the debounce time.

Page 9: Low Voltage Wiring
Low Voltage Wiring Low Voltage Wiring The remote devices described below require low voltage wiring. All wiring to and from these remote input devices to the Control Panel must be made with shielded, twisted pair conductors. Be sure to ground the shielding only at the panel. - Page 10 Low Voltage Wiring External demand limit setpoint input (Optional) External demand limit setpoint allow to change the unit demand limit setpoint via an analog input. The input signal is confi gurable. Input Signal (2 VDC - 10 VDC) External demand limit setpoint <1 VDC Invalid [1 VDC , 2 VDC]...

Low Voltage Wiring External unit capacity output (Optional) Heat Pump (Reversible Air cooled or Water cooled chillers) One analog output refl ects the actual capacity of the unit between 0 to 100% : 2 VDC output = 0% , 10 VDC output = 100% (max capacity). -
Page 12: Chilled / Hot Water Setpoint Reset
Low Voltage Wiring Chilled / Hot water setpoint reset The Automatic chilled/ hot setpoint reset function applies to the arbitrated water setpoint. Three type of Chilled water reset functions are possible in the TD7 setting. CWS’ = Active Chilled water setpoint (after reset) CWS = Original Chilled water setpoint (before reset) CWR = Amount of reset applied to the chilled water CWS’... - Page 13 Low Voltage Wiring Return Water Temperature Reset The Chilled water setpoint reset amount (CWR) is proportional to the difference between measured return and leaving chilled water temperature (TWE, TWL) It is defi ned as CWR = RESET RATIO * (START RESET – (TWE – TWL)) With limits: CWR ...
