4 Start-up Procedure Installation of Ne w Units 1. Fol low all instruction for installation of water source heat pumps as de tailed in the IOM (Installation Operation Maintenance manu al). 2. Disconnect power or disable the circuit breaker to unit. 3.
5 Power Up Sequence P ower Up S equence When 24 VAC power initiall y is applied to the ZN5 10 controller, the following sequence occurs: 1. All outputs are control led of f .
6 Unit Identification Tag Unit Identification T ag The unit identificati on tag is factory mounted and pr ovided for easy identification of an instal led unit. It contains model numb er, tagging, and location informat ion. See Figure 1 . The top portion of the unit identification tag remains permanently affixed to the uni t for identity purposes.
7 General Information The ZN510 controller is a microprocessor-based direct digital controller that controls a variety of water source heat pump equipm ent including: z Standard efficien cy horizontal and vertical units up to 10 ton s. z High efficiency horizontal and vertical units.
8 Pow e r The ZN510 contro ller is powered by 24 VAC . A total of two 1/4-inch quick- connect terminals are provided for 24 VAC connection to th e board. See Figure 4 for ZN510 power requirement. Note: P ower for fiel d installed ancil - lary devices is not availab le from the board.
9 Unit Operation Analog Outputs ZN510 does not use analog outputs. Binary I nputs The ZN510 controller has three available binary inputs (BI). These inputs are factory-configured for the following functions: z BI 1= Low temperature detection (freezestat) (Circuit 2).
10 Unit Operation Low T emperatur e Detection The low temperature detection diagnostic protects the he at exchanger by using an analog leaving water temperature sensor to protect refrigerant circuit 1 and a binary low temperature detection device to protect refrigerant circuit 2.
11 Unit Operation In Occupied mode, th e controller operates according to the occupied setpoints. In Occupied Standby Mode, the unit controller operates according to the Occupied Standby setpoints.
12 Unit Operation 12 4 5 6 7 3 Analog Inputs The ZN510 controller h as five available analog in puts (AI). These inputs are factory-con figured for the following func tions: z Zone = Space temperature. z Set = Local setpoint. z Fan = Fan mode input. z AI 1 = Leaving water tem- perature (Circuit 1).
13 Unit Operation Space T e mperature ZN510 controls the space temperature a ccordin g to the ac tive space temperature, the active heating/coolin g setpoint, and th e space temp erature control algorithm. The ZN 510 controller receives the space tem perature from either a wired zone senso r or as a communicated value.
14 The ZN510 controller receives the fan mode from eith er a wired zone sensor or as a co mmunicated valve. When neither a zone sensor nor communicated fan mode are present, the ZN5 10 controller will default unit operatio n to AUTO .
15 Zone Sensor Zone Sensor The ZN510 contro ller accepts the following zone sen sor inputs: z Space temp erature mea- surement. z Local setpoint (internal or external on the zo ne sensor). z Fan switch. (Optio nal) z Timed overri de ( ON and CANCEL ).

18 Heating or Cooling Control Mode Operation Heating or Cooling Operation For both single and dual com pressor operation, the ZN 510 controller cycles the compress or(s) on and off to meet heating or coolin g zone demands.
19 Single and Dual Compressor Operation Other Modes Occupanc y Operation Unoccupied operatio n normally is associated with eve ning h ours when the space is vacant. In unoccupied mode, the control ler always uses the default unoccupied heating an d cooling setpoints stored in the controller.
20 Data Sharing Master Controller ZN510 can send or rece ive data (such as setpoint, heat/cool mode, fan request and space temperature) to and from other co ntrollers on th e communication link, with or without a building automation system.
21 Configurable Parameters Rover, Trane’s service tool, uses the unit type “heat pump” to determine and download unit con figuration information, such as the default analog inputs, the default binary inputs, and the default b inary output configurations.

Manual output tes t mode (2-second hol d), No diagnostics present. LED blinks (two blinks ). Manual output tes t mode (2-second hol d), One or more diagnostics are present.
23 Manual Output T esting the Heat Pump Configurations The procedure for testing heat pump configurations i s: 1. Press and hold the T est button for at least three seconds to start the test mode. 2. The test sequ ence resets diagnostics and turns of f all outputs.
24 Troubleshooting Questionable Unit Operation Table 13 : Fan output does not energi ze Prob ab le C au se Explanation Random star t observed . After power up, the controller alw a ys ob serves a random star t fro m 0 to 25 seconds. The controller remains off until the random start time expires.
