(2.25 x FLA motor 1) + FLA motor 2 + FLA electric heatnn If the calculated MOP is within 10% of the next smaller available
fuse size, that fuse size shall be used. If not, the next larger fuse size above the calulated MOP must be used.nn If the selected MOP is smaller than the MCA, the selected MOP
must be increased to the next larger available fuse size above the MCA.nn If the MOP is less than 15, it shall be rounded up to 15 amps. This
is the minimum fuse or circuit breaker permitted by code.
nn EC motor nameplate amperage indicates the motor hardware peak amperage while the motor full load amperage (FLA) is limited by the motor’s factory programmed operating range, programmed specifically for each unit size. The programmed operating range is generally only a portion of the motor hardware full potential resulting in the motor FLA being lower than the nameplate FLA. Motor FLA will be reflected on the Fan Coil serial tag and should be used when sizing building electrical requirements.

and Y2 at P1 terminal.
4. If disconnect option is not installed connect line power to the L1 and L2 lugs on the compressor contactor.
5. Accessory relays 24VAC max. Activated by compressor output.6. All 208-230V units are factory wired for 208V operation. If supplier
voltage is 230V, installer must rewire transformer.

Vertical Stack Water Source Heat Pump Submittal Data English, IP Units
Standard 24VAC sequence of operation
Random start delayWhen the unit is first powered “on” the control microprocessor will generate a random number to determine the start delay of the compressor operation (3-5 minutes). This delay is used to prevent multiple units from cycling “on” at the same time. The purpose is to prevent a large power load on the building electrical system after a power outage. After the number, or delay time, is generated the microprocessor will use it to determine the minimum amount of time delay before the compressor is cycled “on” after a demand is received from the thermostat.
Anti-short cycling delayAfter the random start delay is generated the microprocessor will use it to determine the minimum amount of delay before the compressor is cycled “on” after a demand is received from the thermostat. This allows the refrigerant system to equalize in pressure and prevents short-cycling of the compressor.
Minimum compressor runtimeThe minimum compressor runtime of each cycle, heating or cooling, is sixty seconds. Once the compressor is energized it will not de-energize until the minimum runtime is satisfied, even if the thermostat input is removed. Cooling 1st stage (Y1, O)When the microprocessor receives (Y1, O) at the 24VAC thermostat input connection, the unit will proceed with the cooling 1st stage sequence. The microprocessor must receive these signals for two continuous seconds before it recognizes the inputs as valid. Once the input signals are determined to be valid the reversing valve will energize/de-energize after five seconds. The microprocessor will then verify that the anti-short cycling delay has been satisfied. Once the anti-short cycling delay has been satisfied the compressor will cycle “on.” The blower will cycle “on” in low speed fifteen seconds after the compressor is cycled “on.”
Cooling 2nd stage (Y1, Y2, O)When the microprocessor receives (Y1, Y2, O) at the 24VAC thermostat input connection, the unit will proceed with the cooling 2nd stage sequence. The microprocessor must receive these signals for two continuous seconds before it recognizes the inputs as valid. Once the input signals are determined to be valid
the reversing valve will energize/de-energize after five seconds. The microprocessor will then verify that the anti-short cycling delay has been satisfied. Once the anti-short cycling delay has been satisfied the compressor will cycle “on.” The blower will cycle “on” in high speed 15 seconds after the compressor is cycled “on.”
Heating 1st stage (Y1)When the microprocessor receives (Y1) at the 24VAC thermostat input connection, the unit will proceed with the cooling 1st stage sequence. The microprocessor must receive these signals for two continuous seconds before it recognizes the inputs as valid. Once the input signals are determined to be valid the reversing valve will energize/de-energize after five seconds. The microprocessor will then verify that the anti-short cycling delay has been satisfied. Once the anti-short cycling delay has been satisfied the compressor will cycle “on.” The blower will cycle “on” in low speed fifteen seconds after the compressor is cycled “on.”
Heating 2nd stage (Y1, Y2)When the microprocessor receives (Y1, Y2) at the 24VAC thermostat input connection the unit will proceed with the heating 2nd stage sequence. The microprocessor must receive these signals for two continuous seconds before it recognizes the inputs as valid. Once the input signals are determined to be valid the reversing valve will energize/de-energize after five seconds. The microprocessor will then verify that the anti-short cycling delay has been satisfied. Once the anti-short cycling delay has been satisfied the compressor will cycle “on.” The blower will cycle “on” in high speed fifteen seconds after the compressor is cycled “on.”
Fan only mode (G)The fan only mode can only be used with a 24VAC thermostat and will energize the low speed blower when a (G) input has been received at the 24VAC thermostat input connection. When the input is removed the blower will de-energize immediately.
Honeywell 24 volt thermostats Non-Programmable and programmable thermostats use a control algorithm that uses both time and temperature difference from the setting to determine when to turn on stage 1 fan speed low and stage 2 fan speed hi. This logic therefore controls the room temperature to plus or minus 1 degree from set point.

n If the battery is dead or not installed, the thermostat screen will not display the time but will still retain its set point. The thermostat will still function in heating or cooling mode.
nn Remote control for temperature setting, fan speed, on/off, mode and sleep.
Failure codesWhen the system fails, the corresponding failure code is displayed in the failure display area (lower right hand corner of the thermostat display).

ConstructionZehnder Rittling’s heavy duty, industrial grade filters are designed with a one-piece moisture-resistant chipboard frame enclosing media. Standard frames are nominal 1" thick (3/4" actual). The fiberglass media filter consists of continuous-filament fibers bonded together with thermo-setting resin.
Support grilles of perforated corrosion resistant steel or expanded metal are provided on both sides of the filter. The media pads and support grilles are continuously glued to the inside perimeter of the frame, resulting in exceptional strength and rigidity. This design virtually eliminates the possibility of media sag within the frame.

Fiberglass insulation
DescriptionFlexible duct liner insulation is made from strong, glass fibers bonded with a thermosetting resin. The airstream surface is protected with a reinforced coating system, which combines a state-of-the-art acrylic coating with a flexible glass mat reinforcement to provide a smooth airstream surface.
Advantages n Improves indoor environmental quality by helping to control both temperature and sound.
n The tough, acrylic polymer coating helps guard against the incursion of dust or dirt into the substrate, minimizing the potential for biological growth.
n Coating is formulated with an immobilized, EPA-registered, protective agent to protect the coating from potential growth of fungus and bacteria. Duct liner meets all requirements for fungi and bacterial resistance. Tests were conducted in accordance with ASTM C 1338 and ASTM G 21 (fungi testing) and ASTM G 22 (bacteria resistance testing). Note: As with any type of surface, microbial growth may occur in accumulated duct system dirt, given certain conditions. This risk is minimized with proper design, filtration, maintenance and operation of the HVAC system.
n The reinforced coating surface provides superior resistance to penetration of incidental water into the fiber glass wool core.
n GREENGUARD® certification is proof that the product meets the Environmental Institute’s indoor air quality standards for VOCs.

UsesThe recommended temperature usage range is -70 °F to 220 °F (-57 °C to 105 °C) according to method of application. With full adhesive coverage attachment, the surface to which it is applied may operate to a limit of 180°F (82 °C).
Conforms to NFPA 90A and NFPA 90B requirements.
Resistance to moisture vapor flowThe closed-cell structure of the insulation prevents moisture from wicking and makes it an efficient insulation.
