Hot Water Heat Pump Installation Guide
If you have a PUHZ-W50 or PUHZ-W85 you have a Packaged type unit.
.i.e. The Heat Exchanger is enclosed inside the Outdoor Unit
Step 1 – Choose your system type (Page 4-5)
1,
Simple System
The Operation of the Unit On/Off, Mode & Temperature is via the PAR-W21 Wall Controller supplied.
2,
Basic System
The Operation of the Unit for On/Off & Mode is via an external input to the interface. (Supplied by
installer) While the Temperature setting is via the PAR-W21 Wall Controller supplied.
3,
Analog Temp Setting
The Operation of the unit for On/Off, Mode and Temperature via an external input to the interface.
.i.e. Building management system (Supplied by installer)
Step 2 – Decide how power is to supplied (Page 6-7)
1,
Power is supplied to the Outdoor and linked to the Interface unit.
2,
Power is supplied separately to the Outdoor and the Interface unit.
Note: If power is supplied separately Dip Switch SW8-3 should be switched to ON & disconnect the
wire loop in CNS2 on right of outdoor terminals.
Step 3 – Install thermistor (Page 8)
Two Thermistors are supplied but only One is required. Both Thermistors are the same so any colour
can be used for the installation. TH1 is connected to the terminals on Interface Board and sensor
bulb must be installed on the Outlet side of the unit. (Detects Flow Water Temperature)
Step 4 – Install Wall Controller
Step 5 – Setting of Dip Switches (Page 10-12)
1,
From the first table find: system type and On/Off input and Change Mode and Change Temp and
Package Type. Set the Dipswitches according to the Chart.
2,
To disable Cooling mode: SW1-3 should be ON
3,
Set Temperature Range. From the last table on page 10. Select your desired limits for Temperature
Range. .i.e. Underfloor Heating systems will require the lowest setting of 50°C set switches to SW1-6
OFF, SW1-7 OFF, SW1-8 ON.
4,
If you want to have the Set Temperature Fixed. Table on top of page 11. You may choose to
permanently set Temperature setting to 40°C for the Outdoor unit. The Underfloor Heating Company
will control the room circuits via an external thermostat.
Step 6 – Optional: External Input / External Output (Page 11-12)
1,
Connecting External Input. Table 4.5 bottom of Page 11 and 4.5.2 top of page 12.
2,
Connecting External Output. Table 4.6 middle of page 12.
Step 7 – Check (Page 13)
Self test by pressing Check button twice.
