Advance configuration

• Temperature offset: because of the particular location of the touch panel, the temperature at the

thermostat may vary from the average zone temperature. Therefore it is possible to adjust the reading

displayed on screen (or on the phone). The maximum temperature compensation is +/- 9.9 degrees

Celsius or Fahrenheit.

Ex: a thermostat has been installed in a central location near the kitchen. With no compensation, the

temperature reading (the exact temperature) at this location is 70F while the average temperature in the

dining room and the living room is 72F. If the temperature the user wants to read and monitor (schedules,

scenes, etc.) is the temperature in the living room, just enter +2. Therefore, the screen will display 72

instead of 70.

ATTENTION!: the temperature control performed by CARDIO is based on the temperature

offset. Therefore it is very important to set this parameter correctly.

• Hysteresis: used mainly with heating/cooling system based on pulsed air. Say that the screen is

located in a central location but near a heating/cooling bay. With no adjustment, the temperature read

at the screen will always get to the desired temperature much before the average temperature in the

room. Then, the heating/cooling system would always be turned ON/OFF (cycling) on a very short

time basis before the average room temperature is reached.

Adjusting the system gives more inertia to the temperature control

. Maximal temperature adjustment

goes from +/-0.1 degree Celsius or Fahrenheit to +/- 42 2.9 degrees Celsius or Fahrenheit. Temperature

readings on screen will always be the exact temperature as read by the thermostat. Then, with a 2F

adjustment, temperature readings will go to 74F before the system turns off the heat if the desired

setting is 72F.

• CARDIO control type: select the type of heating (cooling) system to be controlled by CARDIO:

1. Central heating:

2. Heat pump RC:

3. HVAC:

4. Heating setback:

5. HVAC setback:

6. Heat pump RH:

7. Heat/cool:

8. None:

• Secondary controller: when available, choose from RCS or Statnet HVAC controllers. Also, enter

number of secondary zones to be controlled (1 with RCS and up to 4 with Statnet). Do not include

here the zone controlled by CARDIO’s thermostat.

• Zone name: press EDIT and enter name of zones (up to 5) to be controlled.

• Freeze detection (yes/no): is CARDIO to detect a minimum temperature and send out an alert? (see

temperature setting below)

• Overheat detection (yes/no): is CARDIO to detect a maximum temperature and send out an alert?

(see temperature setting below)

• Freeze temperature: enter the minimum temperature threshold.

• Overheat temperature: enter the maximum temperature threshold.

!WARNING!: DO NOT USE CARDIO FOR FREEZE PROTECTION. We strongly

recommend to install an auxiliary mechanical freeze protection for this purpose.
