1. DESCRIPTION
The
MT-444 e Faston
has 3 recipe options, each with its control temperature and their differentials (hysteresis), as well as specific keys for triggering / disabling and turn the lamp on / off, in addition to fast freezing functionality. It also has a digital filter, which has the purpose of simulating an increase in mass in the ambient sensor (S1), delaying its response time (thermal inertia) and avoiding unnecessary compressor trips. It also includes an intelligent blocking of functions and a shutdown mode of the control functions.
Product conforming to UL Inc. (United States and Canada).
2. SAFETY RECOMMENDATIONS
- Check the controller for correct fastening;
- Make sure that the power supply is off and that it is not turned on during the controller installation;
- Read the present manual before installing and using the controller;
- Use adequate Personal Protective Equipamenet (PPE);
- For application at sites subject to water spills, such as refrigerated counters, install the protecting vinyl supplied with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we make available as an optional item (sold separately);
- The installation procedures should be performed by a qualified technician.

[,f17]
Enables the evaporator temperature sensor (sensor
S2)
The sensor S2 can be disabled. If this is the case, defrost will be initiated by time.
[,,,0] = The filter operates both when the temperature rises and when it falls;
[,,,1] = The filter operates only when the temperature rise. When the temperature fall, the response is immediate;
[,,,2] = The filter operates on temperature rise and decrease without impact in the control (only acts on display);
[,,,3] = The filter operates only when the temperature rise without impact in the control
(only acts on display). When the temperature fall, the response is immediate.
[,f19]
Intensity of the digital filter applied to the room sensor (sensor S1)
The value adjusted in this function represents the time ( in seconds) for the temperature to change by 0.1°C. A typical application for this type of filter is for ice cream and frozen food frezzers, as , when the door is opened, a mass of hot air reaches the sensor directly, causing a rapid increase in the measured temperature indication and often unnecessarily activating the compressor.

Fan deactivation by high temperature in evaporator
The purpose of this function is to stop the evaporator fan until the room temperature approaches that listed in the project, thus preventing a high temperature and suction pressure which can damage the compressor. If the evaporator temperature surpasses that of the value, the faz is turned off, turning back on with a set hysteresis of 2°C/4°F. It is a valuable resource when, for example, cooling equipment has been inactive for a few days or when freezer rooms or refrigerated counters are refilled with stock.

Evaporator temperature for fan reactivation after draining
After drainage, the fan’s delay cycle is enabled. The compressor is immediately turned on because the evaporator temperature is high, but the fan is only enabled after the evaporator temperature decrease to the set programmed value. This process is required to remove residual heat (caused by the defrosting process) in the evaporator, preventing room temperature to rise.
