If the alarm has been caused by a safety switch which will automatically reset the BMS can reset the ANK Moducontrol. The BMS can reset an alarmed Moducontrol if the Serial Communication Protocol digital line 5 parameter 0 can be switched to 1. Manual reset controls and breaker switches must be reset manually …
The Moducontrol starts the outdoor fans a few seconds after the compressor starts and allows the fans to run to the end of the cooling or heating caller. The compressor stops and the fans continue to run for a few seconds afterword. Check the wiring connections at the MTA, Moducontrol ( M1S-1, M1-1), fan …
The Moducontrol shuts off the compressor and condenser fan motors when the defrost mode starts. The Moducontrol then stops the compressor and switches the position of the reversing valve to warm the outdoor coil. The compressor is then turned back on. The ice and frost build up on the outdoor coil melts …
The Moducontrol supplies 0 to 10 volts dc and 230 volts ac to the Penn P66AA-1C. The Speed Controller ramps up to 90 % of the normal fan speed for 7 seconds and then begins to modulate to the required speed. The Speed Controller provides power to the fan motor for as long as the cooling caller …
The Moducontrol switch # 7 identifies the requirement for fan modulation and adjusts the speed accordingly in DHW mode. The Moducontrol also provides fan speed modulation for low temperature cooling and mild temperature heating callers as required.
Moducontrol dipswitch # 7 to on. Set parameter A to 1. Set parameter E to 1. Set parameter F is set between 60 and 300 seconds depending on the time required to open the three way valve. The TWS switch automatically overrides the space heating controls to provide hot water. Please Note installer level index 0 parameter iu must be set to 2. Domestic hot water heating is …
The SAGInoMIYA RGE pressure actuated speed controller can be used on ANK series units designated as chillers only. The Johnson Controls P66AA-1C speed controller is approved for chillers and heat pumps. It is necessary for Domestic Hot Water Production (DHW). Required for Cooling Operation below 20 Deg. C. Required for mild weather space heating and DHW production.
The production of hot water can be handled in two different ways. Integrated and free standing. The most common method is to integrate the process completely into the ANK control system. (1) Integrated Operation The DHW thermostat sensor is to be installed into the storage tank. The control wires from the DHW thermostat send a signal to a three …
Install the DCPX control to manage the heat rejection from the ANK to the DHW system as the tank comes up to temperature. Spring maintenance. Make sure the outdoor condenser coil has been cleaned with a soft water spray.
Set the maximum hot water temperature not to exceed 50 Deg. C. or 131 Deg. F. (Factory max. 60 deg. C or 140 Deg. F.).
Set timing for the heat pump to start heating DHW after the diverting valve has fully opened. (Change password 30 parameter E to 1. Change password 30 parameter F to 180 sec).
Make sure circulation pump is free of air and is running.
Check piping system for partially closed valves or trapped air. Make sure circulation pump is free of air and is running.
On units equipped with a circulation pump the Moducontrol starts the circulation pump a few seconds after the cooling, heating or DHW caller is recognized. The pump continues to run as long as the Moducontrol receives a demand call. Check the wiring connections at the MTA, Moducontrol (M1S-2, M1-2) and pump motor …
Pump motor has 230 volts. Current is not measurable. Pump motor has impedance shunt to eliminate motor burnout. No rotation. Place compass on motor shaft. Observe rotation. None. Flow switch open. Replace pump assembly.
Check the pump for air. Loosen the center cap 1/4 turn to vent any air in the pump. Use the air vent bleed cap on the side unit to vent any air at the top of the evaporator waterside inlet. If the unit is equipped with a storage tank vent the …
Isolate outdoor unit. Relieve water pressure to zero. Turn off electricity. Disassemble pump. Look for broken impeller, worn impeller or out of balance impeller. Look for dirt build-up on internal surfaces. Clean or replace components if necessary. Reassemble pump. Start and test.
Check all isolating, modulating, switchover, and branch valves to make sure they are open. Check filter to make sure it is not plugged.

The minimum pipe size recommended by the manufacturer is 1.25 ” inside free cross sectional area for all ANK units. System that share multiple units on a common supply or return must have an equivalent inside free cross sectional area to maintain the flow of water to all units without an …
Chillers require slightly less water circulation than heat pumps. The required water flow rate is higher for heat pumps due to the need to complete a successful defrost cycle in the heating mode. Model Cooling GPM Heating GPM ANK030 7 8 ANK045 9 12 ANK050 11 13
The recommended volume of stored water is 10 liters per kilowatt ( or 9.3 gal/ton) in order for the ANK series unit to work properly. The minimum value is 4 liters per kilowatt. Model Normal Capacity Factory Tank Min Clg. Content ANK030 2.51 T 26 Gal 23 Gal ANK045 3.35 T …
The maximum stored water content is determine by the size of the expansion tank that has been installed. The system can operate with between 4 and 10 liters per kilowatt. If the stored water content is greater than 10 liters per kilowatt a larger expansion tank will be required. Higher stored water content …
The expansion tank is factory charged at 1.5 bar when empty. It can be charged with a maximum of up to a 6 bar. The formula is: bar = 14.5 psig P (Bar) = H (m) / 10.2 + 0.3 or P (psig) = H (ft) / 0.433 Charge vessel to calculated …
Glycol mixtures provide valuable inhibiters to extend the life of the system as well as providing freeze protection. Glycol reduces the heat transfer characteristics of the system. The lowest amount of inhibited glycol that provides freeze protection is the correct % level.
