Salus Thermo 091 User manual

Program
Euro-thermostat is a programmable thermostat. It can automatically adjust the
room temperature to a comfortable level when you are at home, and lower it to
save energy when you go out or sleep. What you have to do is to program the
thermostat so that it knows when to raise the temperature. There are altogether
nine programs contained in the memory of the thermostat. Six of them are preset
in the factory and the remaining three are user changeable.
Manual override
If you want to change the temperature temporarily and do not want to alter the
programs you have set, you can simply touch a button to override the current
program.
INSTALLATION INSTRUCTIONS
Caution: Switch off the electric source before installing the thermostat. We re-
commend that the installation be performed by trained personnel.
Select a suitable location for the thermostat. The location of the thermostat can
greatly affect its performance. If it is located where air circulation cannot reach,
or exposed to direct sun light, it will not adjust the room temperature properly.
To ensure proper operation, the thermostat should be installed at an inside wall
with freely circulating air. Find a place where your family is usually occupied.
Avoid close proximity to heat generating appliances (e.g. TV, heater, refrigerator)
or exposed to direct sunlight. Do not install near a door where the thermostat
will suffer from vibration.
Wiring
Wiring terminals are at the back of the thermostat.
You can nd three terminals labeled COM, NO and NC.
It is a typical single-pole, double throw (SPDT) contact.
In most situations COM and NO are used.
Mounting the thermostat
Using the template provided, drill two ø6mm holes in the wall. Insert the wall
anchors and tighten the left screw with 3mm clearance. Fix the thermostat by
putting it over the screwhead and slide it rightward (note the keyhole-like opening
at the back of the thermostat). Tighten the remain screw to lock it in place.
Note: If the wall is made of wood, there is no need to use the wall anchors. Drill
two ø2.7mm holes instead of ø6mm.
USING YOUR NEW THERMOSTAT
The following procedures show how to operate the thermostat. It is recommended
that you follow the instructions and try to operate once before connecting it to
the heating or cooling system.
1, Start

means comfort temperature and

means economy tem-
perature. These two temperatures are user changeable.
Furthermore, there is a xed defrost temperature (7°C)
indicated by  on the LCD. Throughout the operation of
the thermostat we will refer to them as comfort, economy
or defrost temperature instead of numeric values.
Example:
When start or after reset, the time is 00:00,
Sunday. To set the clock to current time (e.g.,
11:23, Tuesday), press d2 times, h11 times

, or press ☼ to set
it to comfort temperature. Or you can use hkey
to pass through the time without changing the
setting.
Since we want to set 13:00 to 18:00 to comfort
temperature and the remains to economy tem-
perature, press

13 times. 00:00 to 12:00 will be programmed to economy
temperature:
v, Press hor ☼ 6 times to move the ashing point
to 19;00:
vi,Finally, press

5 times to set the remains of
the day to economy temperature:
vii,By pressing OK or leaving no key pressed for
15 seconds, the thermostat will return to normal
operation mode.
Note:
i, Program 0, 1, 2, 3, 4, 5 are preset programs. ☼ and

cannot be used to edit
them. But the hkey is still active.
ii, The nine programs are common to all seven days. This includes the three
user-dened programs. This means that if you change one of the user-dened
programs of a day, the same program of the other days will also be chan-
ged.
iii,The setting will change rapidly by pressing and holding the keys.
6, Reset button
There is a small hole at the right of the OK key. This is the reset button. Pressing
it can reset the thermostat into initial status:
Time – 00:00:00; Day – Sunday; Temperature – Comfort: 19°C, Economy: 15°C;
Programs – All seven days set to PROG 1; User-dene programs – Set to comfort;
Manual override – All cleared; Output – Off
Note: Do not use a pencil to push the reset button because the graphite residue
can cause a short circuit and damage the thermostat.
Under an environment with high (+/- 8KV) electrostatic discharge, the product
may not be operated as in normal conditions. The user maybe required to reset
the unit.
7, Dip switches
If you remove the front cover, you can nd three small switches (dip switches).
These three switches are used to control the span, output-on delay and heat/cool
system (This thermostat is capable of controlling a cooling system. For details
please refer to Part 8: Controlling a cooling system.)
Dip switches
7.1, SPAN
Span is the temperature difference between the turn on temperature and turn off
temperature. 1°C or 2°C of span can be selected and the effect is summarized
in the following table:
Span Heating System Cooling System
1°C
O n
when.....
Tr<=Ts-0.5 Tr>=Ts+0.5
O f f
when.....
Tr>=Ts+0.5 Tr<=Ts-0.5
2°C
O n
when.....
Tr<=Ts-1.0 Tr>=Ts+1.0
O f f
when.....
Tr>=Ts+1.0 Tr<=Ts-1.0
Ts: Set temperature
Tr: Room temperature
For example, if you set the temperature to 20°C and span = 1, the heater will
operate when the room temperature drops to 19.5°C and turns off when the
temperature rises to 20.5°C
7.2, Output-on 5 minutes delay
With this switch enabled, the external system will switch on only if it has been
off for more than 5 minutes. If cooling system is selected, this function will be
activated automatically.
7.3, Heat/Cool system select
To select whether a heating or a cooling system to be controlled. Note that nor-
mally for a heating system the comfort temperature is higher than the economy
temperature, while it is reverse for a cooling system.
Span = 2
Cool
Span = 1
Heat
Delay Enable
Delay Disable
8, Controlling a cooling system
By setting the dip switch, the thermostat can be used to control a cooling system.
The operation is similar to that of heating system. However, there are some
differences between them, as the following list:
1, In general the comfort temperature of a cooling system is lower than the
economy temperature.
2, The switching is reversed: The thermostat switches on the system when the
room temperature is higher than the set temperature.
3, There is no more defrost temperature. The snow (  ) and 7°C will not be displa-
yed. If you select program 0 the thermostat will switch off the cooling system.
4, The 5 minute minimum cycle time is enabled automatically, regardless of the
setting of the dip switch.
