General Installation Information
Safety Considerations
HydroZone Control Panel
Installing and servicing heating and air conditioning
equipment can be hazardous due to system electrical
components. Only 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.
Locate the HydroZone panel in an indoor area that
has enough space for service personnel to perform
maintenance or repair. Provide 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 Control Panel
Mounting illustration for mounting hole locations.
Follow all safety codes. Wear safety glasses and work
gloves.
WARNING: 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.
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. Calculate 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 GPM or CFM required for each of the zones.
5. Lay out and size the radiant tubing or supply air
ductwork. Care 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.

Thermostat Installation
Locating the Thermostats
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.
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

Mounting and Wiring the Thermostat
Position the thermostat subbase against the wall so that
it is level and the thermostat wires protrude through the
middle of the subbase. Mark the position of the subbase
mounting holes and drill holes with a 3/16-inch bit. Install
supplied anchors and secure base to the wall. Thermostat
wire must be eight-conductor 18 AWG. Strip the wires
back 1/4 inch (longer strip lengths may cause shorts) and
insert the thermostat wires into the HydroZone connector
as shown to right. Tighten the screws to ensure tight
connections. The thermostat has the same type connectors,
requiring the same wiring. Caulk the hole in the wall where
the wires enter the thermostat.
Note: See the instructions enclosed in the thermostat for
detailed installation and operation information.

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 R and C 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. Connect wires to proper terminal on the pump relay.
(see wiring schematic 97P806-01 on page 4).
5. Replace 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.
OPERATION, displays the current controller setup selection. They are OUTDOOR, TC AUTO, and TC MANUAL MODE. If the
operation mode is outdoor reset or tank control auto, the MODE should display OFF, ON, or EHEAT. If the operation mode
is tank control manual, the MODE should display OFF, HEAT, COOL, or EMHT. OUTPUT shall display the current status of the
outputs (WARM WEATHER SHUTDOWN, STANDBY, C1, C2, C3, C4, or AUX). STANDBY mode is active when the controller
is satisfied and waiting for a call. C1, C2, C3, and C4 will be off and O will stay in its previous state. If the outputs are off due
