THERMOSTAT Æ Select the type of control to carry out:

• Only Heat

• Only Cool

• Heat & Cool



REFERENCE TEMPERATURE Æ

 For every enabled

thermostat in the Z38, users will be asked by parameter whether to

use the internal sensor measure as a reference, or if on the other

hand an external sensor will be used. The same parameterization

field offers also the possibility to choose a proportion between both

measures (Z38 internal sensor + external sensor).

Proportion Z38 Internal Sensor External Sensor

1 75% 25%

2 50% 50%

3 25% 75%

The resulting measure is exclusively used by the thermostat in the

Z38, and cannot be shown through any available Communication

object.

FREEZING PROTECTION Æ Regardless of the status the

thermostat may be (On/Off), when “Freezing Protection” is

activated, the system will be warned to automatically keep the

temperature always above a value (Protection Temperature) selected

by parameter.

¾ Protection Temperature

: This parameter fixes the minimum

temperature the user will accept.

9 Protection Temperature is measured in ºCelsius.

9 There is no connection between the “Set Temperature”

and the “Protection Temperature”.

9 This is the real temperature to be applied as freezing

protection.

9 Thermostat will turn Off when temperature in the room

reaches “Protection Temperature + 1ºC”

OVERHEATING PROTECTION Æ Regardless of the status the

thermostat may be (On/Off), when “Overheating Protection” is

activated, the system will be warned to automatically keep the

temperature always below a value (Protection Temperature) selected

by parameter.
