Gt Crono

Multi-zone Cronothermostat


The Gt Crono is a simple multi-zone contoller suitable for regulating cooling or heating in up to fifty zones. In addition, it can control other components utilising a simple on/off contact, for example, external lighting and irrigation, etc.

Product Information

The Gt Crono has fifty zones, each of which can be set up as a temperature controlled zone, or as a timed control for contact activated components

Ten water pumps can be assigned - if one of the zones set up for temperature control asks for heating, it activates a pump to send hot water through the radiators

There are ten base times - each zone, whether temperature or time controlled, is assigned a base time - this means that if one zone assigned to that base time has its time settings changed, all zones with that base time will change with it

Each zone's control can be altered by use of an external contact, for example, a door switch or a PIR sensor, this conditioning can be used to set the zone to run at a comfort temperature when the room is occupied

Each zone has two working temperature levels, economy and comfort. For maximum energy efficiency, each level can be set individually per zone

If the building is unoccupied, the system can be set in anti-freeze mode. This can be de-activated at a set date and time

Each zone can be allocated up to five operating periods per day. These daily periods can be set individually per day, allowing, for example, the weekends to operate at different periods compared to weekdays

Each zone has its own archive which records daily working hours and total running hours, as well as minimum and maximum recorded temperatures achieved

Clear graph displaying readout of the last 48 hours temperature

The system can provide a minimum and maximum temperature warning for each zone  to an external alarm system

The control unit has a large screen and is extremely user friendly with push button control

The centrally controlled unit has modular interfaces which simplifies wiring
