• Set time using the time and date button.
• To move around the functions shown on the menu structure
of page 12, you start by pressing ‘SET’ several times to skip
past the password setting until you get to the first function
DTO. You open a menu by pressing ‘SET’ and you close a
menu by pressing ‘ESC’. To move to the next menu item you
press ‘+’, to move to the previous menu item you press ‘-‘.
To open a drop down menu (TEMP & FUN) you press ‘SET’, to close a drop down
menu you press ‘ESC’. A menu is open when the menu items reading is flashing.
A menu is closed when the menu items reading is solid. If you don’t touch any
key, the menu setting will be saved where it was left, and then the controller will
automatically go back to the standby mode after 6 seconds.
• ALL TEMPERATURE SETTINGS ARE ACCURATE IN THERMOCOUPLE
SOCKETS, IF RETROFITTED WITH PROBES INSERTED INTO CYLINDER
CASING HOLES (DRILL 9MM HOLE) AND SET FLAT AGAINST INSIDE
CYLINDER BARREL BETWEEN CYLINDER AND INSULATION, THEN
ALLOW 3-5DEGREES LOWERTHAN ACTUAL READINGS WHEN SETTING
CONTROLLER FOR COPPER AND STAINLESS CYLINDERS AND 5-10
DEGREES FOR GLASS OR ENAMEL LINED CYLINDERS).
• Ideal settings For DTO & DTF for use with nMIN set to 30% (recommended) for
adjustable power to pump to create variable speed:
Copper Solar cylinder = DTO 8 DTF 6 (with prob socket)
Copper Retrofit = DTO 10 DTF 8
Stainless Solar = DTO 8 DTF 6 (with prob socket)
Stainless Retrofit = DTO 10 DTF 8
For Glass & Enamel Lined cylinders (ie. Rheem) – DTO 14 DTF 12
heating using the controller through a single pole relay
(via h1 of controller terminal box).
• THET = timing function for heating - there are 3 time heating settings to choose from.
Typical settings are:
• TH1 “ON” at 01:00 50˚C and “OFF” at 07:00 60˚C.
• TH2 “ON” and “OFF” at 10:00 – Therefore this setting will remain OFF.
• TH3 “ON” at 16:00 50˚C, OFF at 23:00 to 55˚C (or if customer only uses half the
cylinder on a daily average basis, leave off by setting ON & OFF at same time)
or adjust to suit customer requirements & allow for probe discrepancies (Contact
Ice Solar ltd if help required).
Note: If only morning users of hot water set night heating back up as priority (ie.TH1).
If only evening users of hot water set late afternoon heating back up as priority TH3).
SETTING UP THE CONTROLLER
Set Points are as per Owner Manual
If there has been a power surge it is a good idea to check the controller to en-
sure settings have not reverted back to factory setting. Ie. if frost symbol has
disappeared or T4 is not showing on screen when scrolling through parameters
(press “+” or “-” to scroll), then this is an indication that system has reverted to
factory default settings.
WARNING: DO NOT make changes to the set points without full understanding
of the controller function. If unsure seek advice from Ice Solar.
• Press any button to wake up controller.
• Press Set THET appears - this is for Auto Time Heating (Time clock) Factory
times are as per owners manual - REFER to Owner’s Manual for adjustment.
• Press Set THET appears, Press “+” CIRC appears, then press “+” PWD ap-
pears, then keep on pressing “+” to skip through password until first item on
main menu comes up ie. LOAD. Press plus to move through the items, see
Owner’s manual for the detailed list, however, the main menu items in order
are LOAD, COL, PUMP, COOL, AUX, MAN, BLPR, OTDI, OPAR, OHQM,
FS, UNIT, RST, PASS.
• Press “SET” to open an item. If it is flashing it is asking if you want to
change, if you don’t wish to change, press “esc”, if you do wish to change,
then press “+” or “-” to make change then press “esc”.
• DTO and DTF and SMX are set to most common installations as per the
owners manual taking into consideration nMin30% for incremental pump
speed. GLASS/ENAMEL lined cylinders do not provide good readings
through so to compensate increase DTO to 12 and DTF to 10. SMX should
also be set at 60, as the maximum operation of the cylinder for enamel lined
cylinders is 70 degrees and this allows for the discrepancy of probe reading
less than actual by up to 10 degrees.
• For low pressure systems that have possible air-locking issues ie. less than
minimum of 2 meters head of pressure maintained above the level of the
collector, then nMin can be changed to nMin100% to assist with flow. How-
ever, it is always best practice for longevity of pump to have good constant
pressure in the system.
NOTE:
Advanced systems that require set points different from owners manual should be
recorded and dated on the owner’s manual for ease of future technical reference
