HDZNE INSTALLATIN MANUAL eneral Installation Information Safety onsiderations Installing and servicing heating and air conditioning equipment can be hazardous due to system electrical components. nly trained and qualified service personnel should install, repair or service heating and air conditioning equipment. When working on equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. WANIN: Before performing service or maintenance operations on the system, turn off main power switches to the indoor unit. Turn off accessory heater power switch if applicable. Electrical shock could cause serious personal injury. HydroZone ontrol anel Locate the HydroZone panel in an indoor area that has enough space for service personnel to perform maintenance or repair. rovide sufficient room to make electrical connection(s). The HydroZone is not approved for outdoor installation and, therefore, must be installed inside the structure being conditioned. Do not locate the control panel in areas where ambient conditions are not maintained within 45 F to 95 F and are greater than 75% relative humidity. The HydroZone control panel should be mounted on or as close to the unit as possible by using the sheet metal screws provided. See the HydroZone ontrol anel Mounting illustration for mounting hole locations. Note: Use longer screws (not provided) to penetrate through drywall into stud. Delivery Information When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. Examine the contents for shipping damage, removing them from the cartons if necessary. If any damage is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage. Installation and Design Steps 1. Decide which areas of a home or office will comprise each of the individual zones. A maximum of twelve individual zones can be chosen. If more zones are necessary, a 12 zone expansion is available. 2. alculate loads using software or other recognized methodology. 3. Use software to determine the equipment size and performance based on the total heating and cooling demands of the building, not the sum of the individual zone demands. 4. Find the peak heating and cooling demands and the peak M or FM required for each of the zones. 5. Lay out and size the radiant tubing or supply air ductwork. are should be taken to avoid under sizing either the buffer tank, radiant tubing and spacing, supply air systems, return air systems, or diffusers. 6. Decide where to locate the thermostats. 7. Install the unit, storage tank and the HydroZone system. 5

HDZNE INSTALLATIN MANUAL Thermostat Installation Locating the Thermostats The thermostats must be located in the room or zone that each controls. Locate a thermostat about five feet above the floor. Do not locate a thermostat where it may be exposed to direct sunlight, drafts or direct supply air. Do not place a thermostat on an outside wall. Follow the same guidelines that apply with standard thermostat installation. If two or more rooms are on a single zone, locate the thermostat in a hallway or area where it can sense the return air from all rooms.

Wiring must conform to local and national electrical codes. Introduction The controller is a low-voltage controller which maintains geo storage tank temperature by controlling the operation of multiple hydronic heat pumps system. Batteries are not required; temperature and mode settings are preserved with the power off. The controller is not a power stealing device and MUST have both and connected. HydroZone Installation 1. Turn off all power to unit. 2. Separate the front and back pieces of the HZ0. 3. Mount the base of the HZ0. 4. onnect wires to proper terminal on the pump relay. (see wiring schematic 97806-01 on page 4). 5. eplace the cover on the base. 6. Turn on power to the unit. Main Screen After exiting from the setup mode, controller displays the main screen. EATIN, displays the current controller setup selection. They are UTD, T AUT, and T MANUAL MDE. If the operation mode is outdoor reset or tank control auto, the MDE should display FF, N, or EHEAT. If the operation mode is tank control manual, the MDE should display FF, HEAT, L, or EMHT. UTUT shall display the current status of the outputs (WAM WEATHE SHUTDWN, STANDB, 1, 2, 3, 4, or AUX). STANDB mode is active when the controller is satisfied and waiting for a call. 1, 2, 3, and 4 will be off and will stay in its previous state. If the outputs are off due to a warm weather shutdown condition, the proper message should be displayed.

Set point B is the minimum tank temperature set point: Tank temperature (TANK_B) range is 70 F to 90 F, and default as 80 F. utdoor air temperature (AT) range is 40 F to 60ºF, and default as 60 F. be changed from the main screen by pushing the U or DWN buttons. Selecting ENTE shall take the screen to the NTLLE SETU screen. This option will maintain the temperature with a tighter deadband and automatically switch the heat pump between heating and cooling to maintain the setpoint. The factory default is 120 F heating and 5 F dead band. All these temperature setting are with increments of 1 F. The dead band is 2 F to 15 F with Increments of 1 F. Tank Temperature Set point is calculated internally by the outdoor reset algorithm, and updated every 30 minutes if this setup is selected. Warm Weather Shutdown: If the warm weather shutdown is selected, the controller will check the outdoor air temperature sensor every 30 minutes. If the temperature is higher than the set temperature selected for 50 continuous hours, then the HydroZone ontroller will enter the warm weather shutdown mode. If the temperature drops below the selected setpoint for 5 continuous hours, the controller will exit the warm weather shutdown mode and return back to normal. Warm weather shutdown selections are None, 45, 50, 55, 60, and 65. The factory default is None. 3. Tank ontrol Manual - There shall be no automatic changeover from heating to cooling or vice versa. Heating and cooling modes must be selected manually. If heating fixed is selected, the default temperature for tank setpoint is 120 F with a 10 F deadband. The set range is 80 F to 130 F, with Increments of 1 F. The dead band is 2 F to 15 F with Increments of 1 F. The factory defaults are 120 F heating and 5 F dead band, 80 F cooling and 5 F dead band, and warm weather shutdown is None.
