Electronic thermostat control Type ETC 1H

For simple commercial refrigeration applications

The ETC 1H is introducing a exible platform due to onboard micro-controller and software dedicated product conguration, perfect for light commercial refrigeration applications. Standard versions with similar functionality as the traditional electro-mechanical thermostats as well as several customized high performance software versions for various applications are available.

The ETC 1H is developed for applications such as:

• Refrigerators

• Bottle coolers

• Freezers

• No-frost freezers with heating element

• Medicine coolers

Electronic thermostat control, type ETC 1H

Features

• ETC 1H can control the cabinet temperature directly

• ETC 1H has low energy consumption

• 1 or 2 sensors (Air, evaporator) and optional remote display can be connected

• Using NTC temperature sensors

• Temperature control independent of barometric pressure

• High accuracy combined with close dierentials and narrow tolerances ensures improved control

• Built in timers enhances functionality

• Optional alarm for over or under temperature in both cold and warm

• Auxiliary relays: 5 Amp for heater, fan, light etc. Eventually with delayed start or/and stop

• Under voltage and over voltage compressor protection (brown-out protection)

• Pressure equalisation protection on starting the device or when voltage drops out (blackout protection)

• Diagnostics and self check of sensors and potentiometer

• Several defrosting methods can be handled:

◦ Time controlled defrosting ◦ Time controlled defrosting with evaporator sensor ◦ Temperature controlled defrosting

• Dual band control of outdoor bottle coolers

• Quick Parameter Programming using PC software tool and Gateway

• Hydrocarbon refrigerant compatible relay outputs

Dimensions and Mounting

Figure 3: Dimensions and Mounting

The controls can be mounted using the nut shown or it can be mounted using 2 screws type EJOT DURO-PT dia. 3 × 7 mm.



WARNING:

By using screw types dierent than the above mentioned, there is a risk of short circuiting the line potential.



NOTE:

All Danfoss knobs have been designed to sit ush against the housing, relieving the load on the spindle arm. Maximum mounting force of knob: 60 N. Whenever using non-Danfoss knobs, please ensure that they are mounted as described above and that the maximum mounting force of knob: 60 N is not exceeded.
